Message:

It looks like AIM mem requests (implemented as damn_you() and
straight_to_hell() back in the days - and still more or less the same in
libpurple it seems) are no longer necessary; the script no longer exists at
the location used in the source and nobody complained.

Nice try, AOL. And hats of to the Gaim developer who thought of this clever
way around it.
