sometimes I see something is being uploaded and I go to browse that user only to be blocked by them. I'm one of these people who can't stand someone who will upload something from me if I can't get to theirs. When I try to kill the upload it does it for just a second and then suddenly starts uploading again.

Incidently, I have set it to not allow (or rarely allow) freeloaders but that doesn't seem to work too well.
