To be honest if you also upload on other file sharing site and torrent site and you upload there first since those site probably are indexing from tpb and you want to avoid that, it will bound to happen since couple vip are probably use those site also as their source.
Before i know torrent, i usually upload my file and post to couple of file sharing sites. That sites are being used by some uploader from couple of private tracker as a source. The funny thing that happen to me was this, couple of my old files that i upload there long time ago are being re upload to private trackers by couple of uploaders from those trackers, and after that it being picked from those private trackers by VIP and then reupload here.
I don't mind that. Why? Because We can't control it since we actually not own the copyright owner coz we are
pirate "sharer" eventough we bought that particular file . Still, there's an honor among "sharer" by not re-tagging but we also can't control that. I never put tag to all my files that i share on private, therefore i can't say they are retager.
Well, for what is worth, they probably don't know that you are the main sources and not taking the file directly from you and reupload here since it would be a bold move. I guess, you uploaded that on other site that they also used as their source or uploader on their site use your site as their resource
I can only suggest you one thing, don't bother with this since the reason we share are for the shake of the sharing spirit itself yes? What else since we actually gain nothing by sharing. Well we actually spent some for seedbox and good vpn just for people to get our files.
Also the main thing why i put my file to tpb, because it will stay on tpb forever if there aren't any malfunction like server error etc. If someone already put here first, be my guest. But that doesn't mean you can't put your own file to tpb also.
ps : hope you can catch what i mean with my broken English also you probably need to start tagging your own files
Nice discography btw, I see why you upset there. If you start tagging, since your upload are unique, if someone retagg that, it will be easy to recognize.
good luck.
