They got off too easy. It's easily billions they earned through this methods. Facebook is the same story. Many of their ad dollars are from scams, and shady schemes, not legitimate businesses. I mean... spending advertising dollars to advertise something pure on a social network where people go to talk with friends and ignore ads..... did you really think it would have a good ROI? it's rare. People often have to resort to making things as shady as possible to increase the ROI and make their advertising dollars worth it.
I can't put what I want to stay in clear words, but you need to be shady in order to make ludicrous money. Examples: Wall Street, casinos, etc. If you want to pure good, you're gonna have to give up some profit to do so.
