What are the benefits though? And how does that fix the problem we were discussing here which is people leaving instantly?
I dont think we should give players the ability to punish each other - a kick is not a punishement, its removing someone from your party who makes the dungeon unpleasent (for whatever reason). Its a tool to ensure you have a good experience - not to sour that experience for someone else.
Reports are not a punishment either - they are reporting an issue to an authority thats able to look into the issue and decide wether a punishment is in order and what that punishment should be.
Seriously, the only reason people are asking for the ability to inflict punishments themself is revenge - they got screwed over, so they want to screw that person in return now. And thats nothing we need in this game - you have kicked and blacklisted the person that was making your day unpleasent and your experience less enjoyable, so they're not a bother of yours anymore.
