I have a experience with this as a man.
Essentially, as a desperate and lonely man one of the last ditch options presented on a website was to date a convicted woman by writing them letters. So I went on the site and these are the few options that stood out to me as a man.
The first was a convicted bank robber. She had a average profile pic and a bitter bio. The fact that she was a convicted bank robber was actually very easy to fantasize about. I am shy, have zero traffic tickets, and introverted, so the idea of dating someone who robbed a bank was oddly erotic. I suspect many of the women fantasizing about your need to speed ripoff or ted bundy live really boring lives working office jobs. If you are in that position, like I was, the idea of dating a bank robber seems like a alluring fantasy.
The next had really good pics for being in a prision. She was chubby but average, not bad looking, but she had a really well written bio. One of the best bios I had ever read, that was really positive and sort of uplifting. I thought, "Oh, she seems so nice: wonder why she is here." Looked on the crime section: Conviction for producing and distributing Child Pornography.
I get why they would go after someone who has killed someone or something if their life is boring. Even if the person in question is actually just average physically, like Ted Bundy. The second woman was not on the physical level of 10/10 attractiveness as the sex offender tinder catfish that incels try to use to prove that women care about looks. She just had a really good bio for the site. If the second woman woman's charges were on a tinder profile with a 10/10 woman I could understand why men would be very interested in hooking up with her. The bank robber woman seemed like a bit of a bitch, even though had a nice smile in her pics, but if she was local and out of prison, I would probably swipe right and see how that goes.
I would not go out of my way to meet either of these people, and would never want to speak to child molester woman irl unless she was like a perfect 10 in real life hitting on me, but I was at a really low point at my life when I was on the prison dating site. Neither of the woman were as hot as the catfish women or Jeremey Meeks.
