Yeah, global upload limit doesn't seem to take, no trouble on per-torrent limit so far though. [EDIT] I stand corrected, per torrent upload limit also blatantly ignored.
Ah, so there are still sane people after all . Err on the side of caution (and thus ban), while doing actual investigation and talking to the devs. Policy I can agree with, yesyes.
Judging from the status bar, µTorrent thinks the peer is local. Could be an issue with local peer discovery. Perhaps disabling local peer discovery could prevent it?
