AFAIK only those sponsored ICO ads are the ones that are blocking by facebook because they don't really like that and there's a news about it.
No, that's not the case. They will block all unsolicited spam posts and comments, if they happen to find any as well.
Okay, so they are also doing some filtering within their users posts and comments.
This is much better so those scammers will get tired of looking for their prey. That's a better way of helping the community and I'm starting to like this deed of facebook.
Eliminating spam posts and scam comments.
