I wish this were a stickied official thread and updated regularly (I know there's a stickied there but it isn't updated and the focus is on changing info)

Trackers that ban for country change:
TorrentGui
PassThePopcorn
BTN

Trackers that can't decide on concrete rules about IP change (they may ban or they may not):
Torrentleech
What.cd (changing details is 99% guaranteed ban)

Trackers that don't ban for country change:
Bitspyder
Animebytes
CHDbits
HDChina
asiatorrents

-please post info on Sinderella if you know

Sinderella is safe. Most asian trackers are safe. I don't believe BTN bans country change.
