In July, uSocial announced it was offering Twitter users the chance to purchase followers on the micro-blogging site. Blocks of followers ranging in size from 1,000 to 10,000, could be purchased with prices starting at $87 (£53).
uSocial said it scours Twitter and identifies the subjects users are interested in. The company then sends members a message telling them about potential accounts they might like to follow.
According to uSocial CEO Leon Hill, Facebook is a good a marketing tool as Twitter, which is why businesses might consider buying followers.
"Facebook is an extremely effective marketing tool as anyone with a large number of targeted friends or fans can attest to. The only problem is that it can be extremely difficult to achieve such a following, which is where we come in," said Hill.
uSocial didn't reveal how much Facebook friends would cost.
