My apologies if this strays off topic, but I wanted to share my recent

We had a collocation customer come in and request a t1 of pots lines for
their servers, then complaints that their "security" software wasn't
working because of our RPF checks.  As it turns out they were dialing up
to a local isp, and sending bulk email using our bandwidth, but the
dial-up's ip.... And receiving the TCP ack on the dial up.  

Very ingenious imho, but I'm not sorry it didn't work out.

Anyone else seen this before?
