In my experience this is a prevalent problem on Commons; whether over issues of personality rights or copyright. Users are fairly dismissive of things that should throw up huge red flags.

For example tonight I came across this: http://commons.wikimedia.org/wiki/Commons:Deletion_requests/File:Rush_limbaugh.jpg Image was quite legitimately questioned; the Flickr image notes are quite a red flag suggesting that it might be a problem. Trivial work with Tineye and Archive.org showed it is a clear copyvio.

But the original nominators comments were dismissed with apparently no investigation.

Stuff like personality rights and copyright should be taken a lot more seriously; with effort made to prove the lack of a problem, rather than demand to have the issue presented on a plate (and then continue to ignore it).
