If account is disable at PTM, you can't see a clear message about that. You only stuck at the pin entering page and it never redirects you to the login page.
Don't waste your time with their IRC as I remember it needs you to register your name and such bla bla so it would be easier to get new invite after clearing cookies,rebooting router, etc and next time use your account as PTM is a very good ratioless tracker.
