This facebook and google ban are actually a double-edge sword. It is good that it can prevent and eliminate the scammers in operation but it is bad for the legitimate ones because they are also affected by this. The ban would lessen the exposure of the legitimate sites especially that Facebook is the largest social media and google is the largest search engine.
Yes maybe, but still there are a lot of crypto ads in google and Facebook, and a lot of them are scams from my point of view. So I am little bit skeptic about this restrictions.
