No offense, but if yedda were only for nice, intelligent people, you probably wouldnt be on here.
Your question is a BIT judgemental. You have to account for people coming from all walks of life with a ton of varying opinions and mores. NICE people wouldnt call other people slutty. INTELLIGENT people would probably realize that the suggestion, albiet crude, might be an option if the question was about revenge...and that if you didnt approve of it, be intelligent enough to offer another solution.
If you signed up to help people, please realize that the anonymity lets people be honest, and that if you plan to make them feel ashamed for their problems or make people ashamed for sharing their life experiences and possible solutions, please go somewhere else.
If you choose to try being proactive... then welcome to the community.
