if he's posting under a new account, he's not banned.
os10geek annoyed a lot of people. have fun as 'placebo' but don't ask to go back.
Perhaps we need to clarify the difference between a banning and a 'change of posting access priveleges'.
In the former, the IP range is blocked. No reading, accessing, anything.
We don't want that person, no matter under what name, as part of the community.
A change of posting access means that that particular persona is no longer welcome. Unless explicitly stated in an email to the person, the length of these is at our discretion. In the case of people who particularly get on our nerves, it is possible that we don't want the persona posting, but the human being can feel free to register a new name, clean up his act, and become a pleasant member of the community again.
It's akin to an exile; you can change your name and your act, and come back unnoticed, but the former you must stay out.
Hope that clears it up...
