Those people will flip the tokens as soon as they get them, and it's usually much less people than it looks like due to multi-account.
Also the quality of the post is very low even for hero and "legendary" members.
If I had a coin I would never ever distribute part of the tokens towards bounties; I'd see that as a kick in the nuts to legit ICO participants.
I think you are wrong and you shouldn't make assumptions for everybody, of course there are some people lacking quality comparing to their ranks but they are the minority. And also bounties can create hype and raise interest in your project.
