I think you're approaching this from a very narrow and naive standpoint. There's no magic that makes this app save anyone from abuse, makes information correct, and that's not even the entire intent of the app it seems. No reason an abuser couldn't use it just the same.

I think if you thought about it you'd realize that his app's format, people posting pics of other people without their permission and commenting on them follows the same mechanism as sites where the people posting ARE abusers, even help track people down...

I was abused and also falsely slandered in different, unrelated incidents. Am I qualified to speak on this?
