I agree! I get "data" from alot of sources and I will PM(email) the original uploader asking for permission to "clone" their hard work elsewhere. Almost always they say yes and don't request recognition but to the ones that don't reply, I try to add a special thanks goes to "original uploader" line to my torrents.
Have you experienced this problem on this tracker? Or has it a been a case of others snagging your hard work from other places and posting it here? If the later is the case please feel free to add a comment to the torrent to the effect of "I'm glad my hard work elsewhere has made it to the tracker!". It is respectful and lets others know who did all the work without seeming bitchy.
