The message
from The Natural Philosopher contains these words:

Why would he abandon the IMM ID now, after so many years?
Did someone say something to offend him?

And Adam before that so he wasn't IMM for 'many years', it just seemed
that way. The earliest post I can find from that particular Adam was in
December 1999.

Well he was International Man of Mystery, till responses to that dropped
to sub zero, then he resurrected himself as IMM, and now its Dr Evil.
I mean. Really. Whatever next?

It could be that it finally sank into that thick head of his that it as
all too easy to turn IMM into dIMM.

Batman and Robin?

Judging by the amount of bath water he needs Fat ******* should be the
next incarnation.
