Even when Spambot posts get deleted, the threads they posted in are still showing up red on my display, like there are messages I haven't read. And their names are often listed as the last ones posting even when the posts are gone!

What's going on?

I was just telling our Dear Leader about that yesterday. I have requested that he bring the matter to the attention of our crack technical squad.

Forum was upgraded... just mark all as read to un-highlight ghost posts/threads. We still can't figure out how to get rid of them.
