It seems like it’s checking all my messages for repeated CAPITALS and then lowercasing all but the first. Or am I mistaken.

It also appears to be multiposting all the hell over the place… 
There is a really neat-o forum called ATMB, in which questions like this are promptly and politely addressed.

If you link to a post that this occurred in, people might not think you’re hallucinating.
Please read the FAQ threads in ATMB. They have lots of useful information. For example:
FAQ - technical issues
I assume you were referring to thread subjects and post titles.
