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.
