A few days ago, there were a few old threads showing up in the General forum but with no new posts. I believe they were due to trial-runs of Yz33d's "bot", where he deleted the added messages after creating them. After clicking on them, they went away for me and never came back.

You might want to try a log-out, clearing your browser cache and cookies and doing a re-login. This often fixes problems with the BBS, and it wouldn't surprise me if the DNS change is causing problems like this for some users.
