I have seen a bunch of ads for trash ICOs on Facebook lately. On the whole, this is probably beneficial for most Facebook users, even if Facebook is trying to position itself to gain most if/when they integrate their own cryptocurrency.

That being said, even if there are bunch of scammy ads on YouTube now by the likes of Tai Lopez, are they any more scammy than his old "Here in my garage" videos, promising lambos and mansions for buying his old courses? I don't really think so, though crypto ones might be more effective ads. YouTube never banned those, in fact everyone has seen them, so I doubt they'll do anything about these new "get crypto rich quick" ones now.
