As far as I know most of the campaign project that are running now still Facebook involved in the category of the bounty.
Where did you get this news, its only a rumors mate? It is still part of the IEO or ICO program so Facebook was still in progress for every campaign.
On March 2018 until June 2018, there was news about facebook going to ban every crypto ads on there. The fact was they did ban all crypto ads, but in a few months later they all removed the ban and only let some Cryptos advertised on there.
Only a few months they have given some restrictions for the cryptocurrency but after few days again we are seeing ads on the Facebook, till now we don't know why again they are allowing the ads posted on the Facebook?
