No, you are not. If you think you should be, but for some reason that automatic system has missed you, you can send an email to PG asking him to ban your account manually.
Er, ... What was the point of this post? I was hellbanned before because I got angry a long time ago.
I mentioned it because I realized I hadn't properly articulated my thoughts. Then I realized it didn't matter in the end. Of course, I guess that realization was wrong.
If you read with show-dead, you frequently see people making similar statements, wondering if the reason no one responds to them is that no one sees their messages. By responding to your post, I was informing you that no, you are not currently banned, and your posts are visible.
The second half was a not-to-funny joke inverting the usual advice about "you should write to PG and ask him to un-ban you". Since you weren't banned, but seemed to think you should be, I was suggesting you write him and request that he punish you for whatever transgression you thought you had made.
