No, only ever had one account. Changed my name on there after some trouble with an SP but that was about a year ago.
Racking my brains further, I have occasionally hotlinked AW pics to reviews or comments on here and on a tranny escort forum, which would probably be against the rules if they could ID me (which is doubtful). But none that I can think of very recently.
I have nearly 40 positive feedbacks which would be a real pain to lose. Happens to SPs all the time, I suppose, so it must happen to punters every now and then.
