In reply to:
May I ask why your profile is hidden?
Because it's a twat of an alter ego of a twat whom prefers the weakness of disclosing no information about itself whilst gathering information about real users so that it is able to rip into those real users, who are are unable to retort in a positive manner because they have no information about the twat.
I've done it myself with alter egos, especially shyster, and it's been done (better) by many others in TW's existence.
Which makes it old hat and really fucking boring.
