Since he is “not part of the team” presumably he has no say in taking something down, especially when it wasn’t his upload.

Would it be appropriate for me to go around asking that Team Blu’s (for example, only because it’s another team) torrents be taken down because ‘we think that’s a good idea’? Would myspleen verify that I had any authority whatsoever to do that to an upload that isn’t mine?

Would it be appropriate for me to go on Negative1’s discogs page and ask that they start removing vinyl releases from his collection?
