As Facebook is the largest social platform in the world it will help crypto advertisers to promote their product/services/projects for sure, as it has helped in the past. We have seen huge ads ran on that platform.

You are wrong, it will not shed light on garbage projects, as it will help the good/honest projects to reach its right audience and on the other hand it will also help scammers to promote their scam/shit projects.

And those scam projects got an easy way to pull naive investors as they did in the past. Facebook doesn't have the ability to identify shit projects imo as the members can do in this forum.
