What was the permaban for? Just spamming? And did you get the why did you ban pobre account too?

Slightly off topic, but when you view a thread but the last poster - ie you in this case - edits his post after, does that thread become 'unread' (or that there's been a new reply)? I haven't noticed it with any other user except a few times after you've edited your posts in Meta (but maybe that's just a coincidence?).
