Am I banned?

BBCode is OFF
Smilies are OFF

No, you’re not banned, but your account is restricted.

So what happened to cause this glitch?

It’s not a “glitch”.
I received complaints about you “trolling” (being repeatedly and deliberately antagonistic). As the forum administrator I had to make a decision whether to close your account, or leave it open with “probationary” access. I decided on the latter course.

A “probationary” forum account allows you to view and post to the forum, but your posts have to be approved by a moderator before they appear. The moderators will reject posts that they consider to be “troll-like”, but other posts will appear on the forum after a short delay.

Your account status will be reviewed in due course.
