Lets compare e-sports to real sports
In real sports, players get competitive and they chirp each other, get in each others faces and lots of other negative things. This is a part of the game and comes with competitiveness.
In e-sports, if you say anything other than "im a positive person, i love riot and please dont ban me for this", then riot will ban you for being toxic. This takes all of the fun out of the game especially since my account is permabanned after paying 200 dollars to getall my shit and after one game OF BEING TROLLED. i get banned because i get trolled and get my game ruined. this is ridiculous.
