Idk, lots of sexual assaulters exist in the offline world. In the social dancing scene, you can meet lots of charming men who will push your boundaries beyond comfort and some will rape. Heard dozens of stories for just the scenes I'm involved in. And you'd think it happens once and then the dude is gone, nope. They stay around for 20 years raping people. And it's very frequently the people leading the community.
I'd love to hear if online dating is statistically riskier than offline but duck duck go isn't helping me much here.
