Just wanted to address one thing:
Facebook banned advertising for ICOs, token sales, and anything relating to cryptocurrency, bitcoin and altcoin alike. Advertising includes
paid campaigns and
sponsored posts, including text-only, images, video etc. Nowhere in the press release does it say that
organic (free) posts are affected. If you post, share or comment on crypto-related topics without trying to promote your post or launch an ad campaign on the Facebook ad network, you should be fine unless you are spamming.
Some people on the forum reported their posts being removed. This is most likely due to their posts being reported by other users, not deleted automatically by the system because of the recent ad ban. These are two different things.
Writing high-quality posts on Facebook and sharing updates from an ICO Facebook page still works. (For now!)
