Re: User / messaging exploit? Causing spam
You know you’ve made it when… LOL
I would highly recommend against closing off the private messaging system or even allowing it as an option. Being able to message someone you are not friends with is a HUGE use case in my opinion. Crucial even. I wouldn’t give users the option to set it to friends only. Or at least… I would like the site admin to have the ability to disable that option.
Alternately… you could use a simple math question… like as in example. LOL
