There was a link to a reddit on a different thread. The OP claimed to be a prison officer. He claimed that as soon as a man claimed he was trans he was given his own cell. Even though there were enough of them to share as most of the other lags did. They also got visits from beauticians.
Eta that's a couple of incentives to carry on, there may be more.
Obviously take this with the requisite amount of salt. It's literally the word of some faceless bod (or bot) on the interweb filtered through my imperfect memory.
