Many people posted links to double bitcoin sites and like I said ICO links, but here's something that those FB's are forgetting: Hyip/ Ponzi sites... yes, Hyip/Ponzi sites are full in FB and I did not see the FB to take action on this, so why are they taking action against crypto and letting the hyip / ponzi sites continue on FB?
I'm sure those are next. Facebook is currently under fire as its negative impacts to society comes to light, and they're trying to clean house. They also made changes to how ads are integrated in the news feed, in a way where they're not as visible, if I'm not mistaken.
HYIP and ponzis are harder to tackle because they don't fall under any "blanket industries" unlike the scammy ICO and crypto ads that seem to be all over. I don't necessarily agree with the blanket ban, but less scams seeing daylight is something I am completely in support of. Hopefully they'll take a healthy middle approach later on.
