ah, let me guess...

"marketing"

Looking back it was so juvenile that I am embarrassed. But I used to sell popularity services for new businesses on MySpace and Facebook. I would get them high friend counts, lots of likes for their page, and even like or upvote certain posts make them appear more popular.

It literally did nothing of real value and was a complete waste of time. And in the case of Facebook probably set them seriously behind in doing actual good marketing because their social graph was completely destroyed by the artificial campaigns.
