If you have a fax machine, let it answer it but don't receive any fax, if there is a live body on the 360-807-5515 end they'll get a nice screaming fax machine in their ear. Afterwards have your fax machine call them back repeatedly, they'll stop bothering you. If we could get a concerted effort from all the people that are harassed by these numbers we could have multiple fax machines dialing in to their sorry [***] and disrupt their business. It's a non-violent way to strike back :)
