The funny part about that is the $15 hijack service was predicated on the flimsy legal fig leaf of somebody writing in an ink signature on a piece of paper and scanning it to port a number (term is an LOA, letter of authorization), same as I have to do when I port a bunch of DIDs between voip providers.

Literally anyone with a printer and a pen can forge any signature and have a fairly high degree of success in the porting process.
