Just as a point of interest, do we block people currently incarcerated from editing?
I have a vague recollection that one of the most voluminous contributors to the original edition of the Oxford English Dictionary, was actually a prisoner...

Certainly he was, an insane killer.
We don't block incarcerated prisoners. Prisons do that, to protect themselves and the public. Prisoners know how to do online fraud, and are good at it.
