I know personally that phone companies do block addresses. Addresses with numerous fraud flags can get permanently banned until certain information is received, and cleared by an actual fraud person. It is rare, but there are fraud department employees that work with this kind of thing as a full-time job.
I only have this information on phone companies, and know nothing about Directv.
OK, This I could see!THe local cable company here has started doing this. Enough non-pay disconnects at one address and that address gets blocked from service.
