i would guess it would be something like:
1)it has to be someone with the rights making the complaint - e.g. if i get upset someone made a better jimmy anderson than mine and he's getting all the downloads, my complaint will not be enough
2)that Jimmy will be taken off the server, but they wouldn't be able to remove our local copies, so it's too late
3)if the same person repeatedly uploaded the same players they might have their CA account closed
4)as soon as one player is deleted, 1000 other versions of the same player will be uploaded
it's like youtube really... they don't approve of the copyright infringement, they will remove reported abuse, but actually protecting your "rights" is an exercise in futility
incidentally, i was thinking about this the other day... we here at PC are very anit-torrents and piracy etc. but we have no compunction in linking youtube vids that are also an infringement of copyright (and have the same impact as pirating a game, since the creator doesn't get performance royalties), and we certainly have no problem infringing sportsmen's image rights... it's quite a moral maze...
