We had a couple of these. Both users had system:anyser write or all
priviledges on the public_html folder. Strangely, one of the user's home
folder was system:anyuser none, so I'm guessing the user had disabled
their web site at some point. We had to educate the other user. So far,
we've only seen two users have these spam files.
