My father is currently in a federal prison. I do not want to reveal sentencing, names, etc. but I deal with Jpay on a daily basis.
Their core currency is 'stamps' if you are technologically literate.
It is $4.50 to be able to buy 12 'stamps'
It takes one stamp to send an email, plus one stamp per attachment.
Beyond this, there are music 'credits', video call 'credits', etc.
It is a fucking racketeering ring. I literally keep a Windows laptop so that I can have video calls with my father because its incompatible with OSX and Linux (Ubuntu 14.04 in my case)
Would love to hear a way to make a difference here...I've thought of nothing.
