Their profiles list their mailing address and those interested in making contact can write, literally write, to them.
Understandably the Sensible Sentencing Trust is appalled, with a spokeswoman saying it was "was hugely concerning that members of the public were endangered by being exposed to high risk offenders".
Fair call, but those members of the public would have to knowingly seek out these profiles on the clearly labelled Prison Pen Pals Facebook page, and, if choosing to take it further, would have to put pen to paper, or type, a letter and send it through the post.
Since this week's story came out, the Facebook page has been made private, so interested parties would also have to take the extra step of asking to join.
After all that they would be the ones exposing themselves to high risk offenders.
So should prisoners even be allowed to have an online presence like this?
Corrections' website lists one of its target "outcomes" as such: "Offenders' legitimate health, physical, cultural, spiritual and social needs are met."
Social needs. I'm not sure that should include advertising themselves on what could be seen as a dating site.
But really, as none of this appears sanctioned anyway, and as distasteful as it may seem to some, are there any rules being broken?
