In my opinion, they can not completely ban advertising, or will make some of its part paid, and only so will regulate it, so let's see what will happen.
Instead of "banning" the ads, it would be better if there is some sort of rules/terms/requirement for the concerned party before they can use any advertisement platforms before they can place their ads. Something like money guarantee or M.O.U will profit both of advertisers and the platform, and even the consumers too. If this could happen in future maybe it could benefit any attached individual to bitcoin as well as could help in decreasing the chances of fraud on this platform
