Probably they are people who come into contact with some of your customers
and are making educated guesses about URL's. Like, if I got an email from
joe.schmo@foo.com, there's a good chance that www.foo.com/~joe.schmo exists,
and if I think I'm clever, I might go to it to see what's there. Any user
out on the internet who sees an email address of one of your people has
enough info to try and find their ~userid.

IIRC, classically identd. This daemon is useless except for people who do a
lot of unix-box to unix-box work. IRC requires it but mIRC spoofs it
rendering it's usefulness laughable. Save some RAM and remove it.
