But it's not the only possible way to violate someone's personal space (or be creepy) in an internet discussion. You could say "Last night had this strange dream where you were being eaten by lion" or "I think I'll make a poster with your photo and put it on my bedroom ceiling". The possibilities are endless. So you can either disallow all personal communication allowing only professional/on-topic stuff (maybe also making everyone use Esperanto so there are no misunderstandings) or you have real humans judging if someone is being a jerk based on their own understanding what "jerk" means. The later is how the real world was doing it for thousands of years (though this is also changing). When a child goes to school she/he is expected to behave in some normal way - parents are supposed to help create that behavior when upbringing the child. And if at school the child does something bad, they call the parents and then the parents are expected to explain the child why it is bad and make sure that doesn't happen again. Summoning the parents is (unfortunately) not an option here, but warning and banning people should work.
