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_limba…

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).
