Emiliano De Cristofaro, Arik Friedman, Guillaume Jourjon, Mohamed Ali Kaafar, M. Zubair Shafiq
TL;DR
Facebook page likes are treated as a measure of popularity and profitability, yet systematic comparison of legitimate promotion and like farms has been lacking. The paper compares both using honeypot pages and finds that farms range from bursty bot-like operations to stealthier, socially connected behavior; it also finds overlap between farm-associated and ad-attracted likers without direct evidence that the latter came from farms.
Problem
Facebook promotion methods had not been systematically analyzed, despite the relevance of understanding fake likes to improving social-network fraud detection and mitigation.

Abstract
from arXiv · showhide
Facebook pages offer an easy way to reach out to a very large audience as they can easily be promoted using Facebook's advertising platform. Recently, the number of likes of a Facebook page has become a measure of its popularity and profitability, and an underground market of services boosting page likes, aka like farms, has emerged. Some reports have suggested that like farms use a network of profiles that also like other pages to elude fraud protection algorithms, however, to the best of our knowledge, there has been no systematic analysis of Facebook pages' promotion methods. This paper presents a comparative measurement study of page likes garnered via Facebook ads and by a few like farms. We deploy a set of honeypot pages, promote them using both methods, and analyze garnered likes based on likers' demographic, temporal, and social characteristics. We highlight a few interesting findings, including that some farms seem to be operated by bots and do not really try to hide the nature of their operations, while others follow a stealthier approach, mimicking regular users' behavior.
1. INTRODUCTION
Facebook page likes are treated as a measure of popularity and profitability, while businesses can promote pages through ads or paid like farms. The paper uses honeypot pages to compare those methods and finds both conspicuous and stealthier farm behavior, alongside overlap between farm-associated and ad-attracted likers.
1. INTRODUCTION
- Facebook page likes are used as a popularity measure, and estimates of their expected revenue range from $3.60 to $214.81, with one estimate at $8 per like.Source: §1 · p. 1
- The study compares Facebook page-like ads with several like farms by promoting 13 honeypot pages and analyzing likers’ demographic, temporal, and social characteristics.Source: §1 · p. 1
- Like farms showed two patterns: some delivered likes in bursts through disposable bot-operated profiles, while others gradually mimicked regular users using well-connected networks.The stealthier farms kept likes per user low; the study also found overlap in pages liked by ad-attracted and farm-associated users, but no direct evidence that campaign likes came from farms.Source: §1 · p. 1
2. RELATED WORK
Prior work studied fake accounts, spam, and detection patterns, but much of it relied on passive observation or lacked ground truth. This study instead uses paid honeypot campaigns to attract and analyze fake likes directly.
2. RELATED WORK
- Earlier studies used passive measurements of fake accounts, spam, and social relationships, while this work actively engages fake profiles through paid campaigns.Source: §2 · p. 2
- Earlier Facebook, MySpace, and Twitter honeypots used profiles designed to look legitimate; these honeypot pages explicitly said they were not real and attracted profiles through paid campaigns.Source: §2 · p. 2
- Paid honeypots attract fake likes to empty pages and provide ground-truth data, whereas Beutel et al. identify groups sharing page likes without ground truth.The authors say some farms emulate regular behavior and that their measurements can complement the detection technique.Source: §2 · p. 2
3. METHODOLOGY
The study deployed 13 intentionally empty honeypot pages, promoted some with Facebook ads and others through four like farms, and monitored likes and public profile information. Its scope was limited by budget to 13 honeypots observed for a few weeks.
3. METHODOLOGY
- The researchers created 13 empty “Virtual Electricity” pages, with five promoted through Facebook ads and eight through four like farms targeting worldwide or US users.The page descriptions asked users not to like them; each page had a different administrator account.Source: §3 · p. 2
- Like activity was crawled every two hours, then daily near campaign ends; public profile data supplied liked-page and friend lists, while Facebook reports supplied aggregated demographic and location statistics.The study identified more than 6.3 million total likes by users who liked the honeypot pages and more than 1 million friendship relations.Source: §3 · p. 2
- The limited budget allowed monitoring only 13 honeypots for a few weeks, making the work an exploratory study that could be extended with larger, more diverse campaigns.Source: §3 · p. 2
- The campaigns collected 6,292 likes in total: 4,523 from like farms and 1,769 from Facebook ads.The BL-ALL and MS-ALL campaigns remained inactive despite advance charges; excluding inactive campaigns, AL-USA garnered the most likes and FB-USA the fewest.Source: §3 · p. 2
- The researchers encrypted collected data, did not redistribute it, and analyzed only aggregated statistics, while acknowledging that paying farms to generate fake likes raised ethical concerns.Source: §3 · p. 2
4. ANALYSIS
The analysis compares liker demographics, timing, friendship networks, and page-like behavior across Facebook ad and like-farm campaigns. It finds distinct farm patterns, including burst-like delivery, varied network structure, and evidence of profile reuse.
4.1 Location and Demographics Analysis
- Worldwide Facebook targeting yielded 96% of likes from India; FB-IND, FB-EGY, and FB-ALL skewed younger and male, while farm liker demographics were closer to network averages.SocialFormula likers were mostly based in Turkey regardless of whether the campaign requested US-only likes.Source: §4.1 · p. 3
4.2 Temporal Analysis
- Except BoostLikes, three farms delivered likes in short bursts; BoostLikes instead increased steadily like Facebook ads, suggesting automated versus possibly human-operated strategies.AuthenticLikes garnered likes from more than 700 profiles within the first four hours of the second day, with no later likes observed.Source: §4.2 · pp. 3–4
4.3 Social Graph Analysis
- Friend lists were private for almost 80% of Facebook-campaign likers and about 75% of BoostLikes likers, versus about 40–60% for other farms; visible friend counts are lower bounds.BoostLikes users, and to a lesser extent AuthenticLikes users, had higher average friend counts than users elsewhere.Source: §4.3 · p. 4
- BoostLikes’ dense ties fit real users or fakes mimicking them; SocialFormula pairs or triplets may limit network-wide exposure, while AuthenticLikes–MammothSocials ties suggest one operator.The analysis also found many isolated pairs and triplets for SocialFormula, AuthenticLikes, and MammothSocials, but a well-connected BoostLikes network.Source: §4.3 · p. 4
4.4 Page Like Analysis
- Median page-like counts were 600–1,000 for Facebook-campaign users and 1,200–1,800 for farm users (except BL-USA: 63), versus 34 in the baseline sample.Campaign similarities suggest profiles were reused within farms and sometimes shared across farms, including AuthenticLikes and MammothSocials.Source: §4.4 · p. 5
5. CONCLUDING REMARKS
Like farms show two distinct operating styles: some deliver conspicuous bursts through botlike profiles, while others mimic regular users through well-connected networks. The study also identifies detection-relevant profile patterns, while noting that the honeypot campaigns and observation period were limited.
5. CONCLUDING REMARKS
- Some farms, including SocialFormula and AuthenticLikes, show large bursts and few friends per profile, while BoostLikes mimics regular behavior through a well-connected network and keeps likes per user low.BoostLikes profiles also had a high number of friends and a “reasonable” number of likes.Source: §5 · p. 5
- Only one BoostLikes account was terminated after a month, compared with 9, 20, and 44 for other farms and 11 from Facebook campaigns.The authors say these terminations may indicate disposable fake accounts, while BoostLikes’ resemblance to real users makes detection difficult.Source: §5 · p. 5
- Although ad-attracted honeypot likers differed from typical users, these results do not show Facebook advertising is ineffective because campaigns were designed to avert real users.Source: §5 · p. 5
- Demographic, liking, temporal, and social-graph patterns among fake likes can be exploited by like-fraud detection algorithms.Source: §5 · p. 6
- Future work calls for larger, more diverse honeypots, longer tracking of removed likes, and investigation of possible fake-like origins including malware and social engineering.Source: §5 · p. 6
