I can't say anything conclusively but I thought the extent of what happened to you is that you had to re-establish an A2K account due to your forgetting or changing your email account or some such. I've been around for more than 10 yrs but despite that I don't follow the history of many of these bans so I'm certainly no authority. However, I don't recall you ever being banned. I only recall the issue where you had an account change and/or redid your nickname because you didn't have your account from which you had originally established your A2K-Abuzz presence - or something like that?
Either way, to me you add value here as you are bright, add color and have a different POV than I do. Occasionally I read your comments and find that you keep my interest, so I'll add my welcome back to you.
