I'm not a man, but I've seen some fucked shit happen to them.
One guy was a super nice guy... but fell in love with a crazy woman. They had a kid. Divorced soon after. He had to pay out so much money to her during the divorce already, even though she threw them into massive debt during the brief marriage, he was responsible for the debt she hid from him as well because the IRS dgaf. But she wanted child support too.. the judge granted both custody. She decided she wanted custody of the child. The child is too young to realize what they're doing. He worked and she was a SAHM so the kid was obvi very attached to her. So she accused him of sexual assault on the kid, and coached the kid to tell the police what happened. He was thrown in jail and arrested while they investigated, his face/name plastered on the local news (small town, EVERYONE knew) for it, everyone knew his ex was batshit, but something so grave and towards a man? ... There are people who still don't talk to him because apparently if you're a man pedophilia charges = automatically guilty. Honestly, the ONLY reason he is out of jail so fast is because she texted his friend admitting she lied about it and he did the right thing. He has to forever live with the embarrassment of not only his reputation being fucked... but seeing his own child accusing him of something his ex peer pressured the small kid into doing killed him inside. She keeps up with the lie too, despite him being out of jail, trashes his name any chance she gets, and sends the child to therapy for a sexual assault that never happened. AND even though he was proven innocent, the court STILL gave her custody "just in case". He has never been the same dude since, stopped talking to everyone, can't find a good job in his town so he had to move, is forever ostracized 'just in case' because people just assume the justice system wants pedophiles running around free.
Because he liked a girl and she thought he had more money than he really did. Not a wink of anything human in that woman's eyes.
I've seen other men with horror stories of young school age girls accusing them of sexual assault because they liked their teacher and hated that he didn't reciprocate. They didn't like the rejection, so they accused him of sexual assault to try to blackmail him into sleeping with her.
Having a lot of close personal friends that are male... Most of them are terrified to be left alone around peoples' kids lest they be accused or judged of being 'creepy' for simply liking kids without being a father themselves. Male teachers have to constantly very carefully watch what they say/do lest they be accused of anything inappropriate. It's just SO easy to do that to them. I think the fake sexual assault/rape claims and the custody battles are some of the worst things I've seen my male friends go through.
