Yeah I definitely agree with you on the last part - its just that voting on users who share "their" photos but don't verify in any way that its actually them leads to more new accounts faking their persona because they see it as easy Money. I've been voting on intro posts for a year now and most users that join and check introduceyourself section or have been invited by friends know that verifying they are "real" gives them more rewards and eliminates the fake ones at the same time.
The only reason I bring this up is cause I've noticed many fake ones recently which could have been caused by big votes on previous fake ones.
