There is a teergrubing news server around, which sits there pretending
to be a news server and absorbing and throwing away everything posted to
it. At least one ISP used it to get a bunch of notorious spammers whose
contracts with the ISP stopped them from being dumped to throw their
news into a black hole for months on end.

It is an ORB, but GNOME uses ORBit, not omniORB.

Numerous FTP servers also require that.

I've got a masquerading identd that runs on a masquerading host and
forwards identd connections to the host they're coming from on the far
side of that host.
