What about sending messages to a specific .onion address to unmask you?
If you send a unique request to http://foobarbaz.onion/?id=50108560 (or
ip=...) you might be able to associate a specific address.

It may be that this is not as easily possible since I suspect Tor is not
as susceptable to a line-oriented attack, so maybe it's not a concern...
I dunno.
