I think not, until now ICO ads are still allowed to be promoted via twitter platform, google, or facebook. It may be just a bluff for ICO project providers to work with companies by dividing the profits from already marketed coins.

It seems that the ban is only for ICO adverts that they deem to be scam. They do not want to be part of a system that will steal peoples money in the name of investment. That is the main reason for the ban. It is a blessing in disguise in that only well articulated project will be bold to come out for ICO.  

it's just that scam ICO's are using these social media platforms to get money from people, probably targeted to the newbies of the crypto world

The good news is Facebook may unban crypto ads. If that happens then twitter can follow the same step. But at this moment, we are facing a problem with Twitter. Twitter has banned crypto ads that's why ICO project's twitter account or bounty hunter's twitter accounts are getting suspended. Hope twitter will unban crypto ads very soon. We really need their support.

People are still able to write blogs, make their videos, and when you have some influential people do these even talk less about it, more people will become aware of it. Banning advertising is okay I guess since it eliminates a lot of scams and advertising scams we've seen all over. These mainstream media do not want to be subjected to some fraudulent ICO or any program involving electronic money. Bitcoin will not be affected by this because now, even without advertising, bitcoin is being talked about.

As far as i know, facebook revised its first decision about the banned thing and just ban the ads of ICOs but not the bitcoin it self, or somewhat they just add standards on allowing ads to be launched. Maybe these those social media did not see the real value of accepting bitcoin as of this moment. Soon they will realize it and it may be late, but atleast they do. As of this moment bitcoin rise and that may be a factor for them to realize the capability of bitcoin.

It has not been implemented till now and there is no official declaration. I do not think that they  will do that.

Twitter is  prohibit advertisements for ICO, token sales, and cryptocurrency wallets. but Its not good news for me because i am join Twitter campaign on bounty on bitcointalk and reword some free crypto coin.

Facebook, Tweeter and Youtube do not ban Cryptocurrency ads but they commemorate, because banning and commemorating it is different.

Because now the evidence Tweeter has launched its own token, and it could have an impact to the Bitcoin price increase.
Then Facebook also followed his word akn creating Cryptocurrency coins.
