@lololulu19 This sounds quite odd, and far exceeds my technical knowledge of how the site works. Perhaps the help desk or a moderator could step in.
I think I know which studio you mean (I don't like to mention names in a public forum), and while I'm not a follower of their genre, I see very little of their material on the site. If gt.rent gets lots of takedown requests and doesn't want that material on the site, perhaps it should be added to the "forbidden" list, and/or a note to you asking not to upload it. (I note that I can find LOTS of their stuff on two other gay porn torrent sites I look at.)
I also note your comment about that studio going downhill. That seems very common, especially when studios change the kind of model or film they produce. For example, another studio starting with "S" was bought out about ten year ago, and their models changed from being collegiate twunks to 30-ish semi-hunks. That appeals to a different audience. And then there are those studios that have disappeared--I miss SEVP, perhaps because I come from that part of the world....
