There isn't but you don't really need it.

You can create a bitcointalk account via TOR services and use it also without having to leave TOR. So that's a good integration most websites don't have.

You may need to pay a little fee to remove the shadowban from yourself as a TOR user but that's also a kickass way bitcoin allows to anonymously prevent IP bans for legitimate users without having to go through silly hoops that could also be botted like most websites.
