To the first question, I typically send a PM to the uploader, and ask them to remove all outside links from descriptions (to other torrent sites) and MOST comply with that request, no problems, because on the encoder's who upload to ET, on their homesites, they don't allow that either... SOME on the other hand, get pissed off, leave me bad reviews, etc, (which I do not give a damn about everyone knows what I do for ET so if you dont like me fuck you
) and then, if they still don't remove, usually our AA's and such give them warnings, or I'll go and remove it myself. I've had a few incidents with assholes, and believe me, some are assholes. All I do is shrug it off and go about my business, if they want to be stupid, then let them. You are a red if you feel you've exhausted all options then yes do what you must do, but don't act in spite, try to make a positive resolution, (sometimes you can, sometimes you cant), and then act upon what judgement you feel is best for the situation.
To respond to the second question, the answer, is simply, NO. LoL. I agree but no many will upload the same thing and it's pointless yes, but it also allows there to be backups if one dies, etc, and it would be pointless to stop OUR uploaders from doing this when ET is an index site, and automatically indexes torrents from other sites, so of course we will get dupes. Maybe we could just invent a disease that kills off all the worlds stupid people? That's the ultimate solution eh? Oh Noes!!!! I wouldnt wanna be compared to Hitler, but thats just my opinion
