you dont need a warning to know timmy is trying to be a dick head because he is a dick head by trolling so why the fuck not just save the time of other players and just ban them on the spot instead of 3 weeks later and 40 trolled games later huh
Because if one game of "trolling" was enough to get permabanned, everyone, you included would be banned from the game.
Riot likes off meta picks hell I had an as he vaynes Botlane in my sliver 1 game the other day and the rules are as long as what your doing is in the teams best interest then you are fine but like when I play shaco support if your team flames and doesn't try then its there fault
