My 2cents.

Overall,its not very nice to ask someone to leave.coz everyone has the rights to play.

But as a community when you also play with other,it is not n8ce when you are not honouring the game and you fellow community (i.e flag when all fighting,not playing as a team etc).

General rule: respect others and be respectful.the line is drawn between rude and polite.

P/s: exception to onade if you are reading this
