This has been explained before - probably on an old thread. Some while ago, the 'Cat went through a near-terminal event - the way computer systems do, from time to time. It has been lovingly put together from the scattered fragments, but anomalies remain. Threads dating from before the NTE are scrambled (posts to these threads made after the NTE should be OK), if you visit the members photos section you will find every photo is doubled, and the search function is up the swanee. Think of it as the side effects of resurrection.

Even as we speak, thousands of nano-joeclones are swarming over mudcat central, splicing together the severed ends of reality and trying to make sense of it all.

Or perhaps not.

I'm just glad the place is here, mudquirks and all.
