I was "placed into a cell" on another message board.  The moderator message said I had to post a message of apology in the cell or I'd be banned permanently.  I was "placed in the cell" because they had given me two infractions for violating subjective rules of posting.

I wrote the moderator telling him/her that I wasn't in a cell, I was still able to go outside and do whatever I want.  They can't put users in cells, users decide whether to use their service.  If they sent me a message apologizing I'd consider returning to their site and viewing the ads on their pages.

They banned me permanently.  Well, they banned a certain IP address permanently.  I'm still not in a cell, and I am not banned, only one computer's IP address.
