The well-known acronym of "YMMV" (Your Mileage May Vary) - or the
Canadian alternative of "YKMV" (Your Kilometerage May Vary) - comes
to mind as the effects seem to be somewhat inconsistent.
For example, I'm not seeing names of farm animals and vehicle brands
intermixed in the third level of the hostnames anymore, and I wonder
how long the pattern you're encountering will last.

I agree. Any system that shows consistency is eventually going to
be countered by spammers, so it's a constant uphill battle. :(

They're no longer bouncing from those addresses? I guess that's
progress of a sort.
I agree with your diagnosis -- it does seem like they really don't
care, and that they have an exploitive attitude about internet mail.
