FunkyImma edit this post as i obviously didn't read this thread thoroughly enough and just shorten it to this:
report this to the police, why post it on this stupid ass gaming form, banning her isn't gonna do shit, report her to the police
You can actually both ban someone from your community and report them to the authorities, you dont have to choose only one.
Why would you state there is insufficient evidence for a ban, but advocate for people to go to the police?
Also your point about not alerting a predator that you're onto them so they arent dissuaded from continuing to prey on people, all so that you can "get more dirt on them" is so backwards it hurts.
