I found another drawback of using Tor 
I have to enter capcha each time I send PM and I have to wait 360 seconds to send it (even if I didn't send PM's today at all I all because of someone sent PM using the same Tor exit node). I think It sould be 360 seconds per account not per IP.

the last time of posting is taken from your IP but how long you have to wait in seconds is calculated using your account's stats (rank). if I'm not mistaken.
