All dating sites are moderated, to some degree. At least the mainstream ones. I can't think of one where you start by posting your home phone and address and full name.
You start by sending messages, establish a relationship. Then you elevate it to messaging/calling via other platforms or real world meetings at your own pace.
It's not for concealing that you're a dick (well, it could be), it's more for protecting you from who knows how many people with who knows what intentions. It's not a guarantee, but it's a filter that works fairly well.
How could this protect anyone from anything worse than the occasional verbal abuse? Real bad people with real bad intentions will most certainly not be frustrated by some automatic word filter or a ban on dick pics. They will probably be the /last/ ones to do anything obviously fishy. You just can't be a sneaky bastard luring in innocent victims and an obvious prick at the same time. Unless you are doing some amazingly charismatic virtuoso double bluffing, I suppose. Or you're just looking for a willing victim looking for a perp. I think the whole idea is beyond stupid.
<s>Sounds like an attractive place to me!</s>
