Facebook bans Crypto ads. Safe measure for community OR a conflict of interest?!

Facebook has banned ads for crypocurrencies. With so many ICO scams happening, this seems like a good thing to keep the community safe.

Let us also understand that, in a case of ICO scam - Facebook is merely a platform that promotes ads and hence not directly responsible for any consequences. By banning these ads, Facebook is turning down millions of dollars worth ads. Mr Zuckerberg's being a crony capitalist, this move doesn't seem very Facebooky. So MAYBE, Facebook is consdering it's own coin? Maybe adapt a model similar to steemit? The new coin would be a very smart move now that Facebook has it's own marketplace.

or MAYBE, this is just to distract us from the alien invasion?

What are your thoughts fellas?
