Banned, or muted? I was muted for posting too many links (I found nothing about this in the Terms) I was about 15 min. maybe. Slap on the wrist, but learned my lesson. (Of course, if you missed one of those numbers, that gets very serious. Or maybe the "nephew" part tripped an automated response.)
Cards on the table- I did something stupid, and am now returning from a week-long ban. Very relieved it wasn't longer, or permanent. For future reference, if you get banned, you can still access the site, just not chat rooms. There is an Appeal form under "Support"
