Google + ICO ≠ ❤

I see some anonymous reports about Google infromally blocking ICO ads in search queries. Looks like Google is about to jump off the train of ICOs and any content related to it.
Formally, Google has no policy about content or ads related to ICO, but many ICOs and bloggers report, that the content they promote drops down by Google without any reasons and/or warnings.

Currently, there is no official news from Google or anyone related to it, but IMO, as Facebook already did, Google will completely ban the fast-growing industry very soon. Is it because of the amount of unqualified ICOs, which scam after raising funds, or maybe it is connected with frauds around cryptoinvestments at all? Personally I have no doubts, these are protective measurements until SEC or whatever organization will publish legislation to cryptocurrencies and the whole variety of tokens existing.
