maybe of the most nonsense topic so far 
After doing some research and digging up through some topics you initiated on the server, I'd advise you to thread lightly and avoid mocking people who're making basic inquiries. At least try to give people the level of respect and understanding you expect to get in discussions
@inzamix In all honesty, those are all dick moves (at lest for me personally), but at the end of the day, the guy who hosted the game has the right to manage it however he likes. I wouldn't dig deeper and discuss reasoning behind it (because it's obvious), I can only advise you to start hosting games yourself so you can manage them however you like.
Edit cause I haven't really addressed the question (I'm an idiot) - there are no rules in regards to thiese specific circumstances. Issuing warns / bans for this would probably be counterproductive since you have easy workarounds (e.g. hosting games yourself).
