Riot didn't need to investigate fl1pzjder......

He will lose his job anyway kekw

That isnt relevant
If Riot finds it necessary to act both Flip and TenTen wont be allowed to compete in general, since they broke the code of conduct, instead of just getting kicked from their team like TenTen did

Personally im pretty sure the "investigation" is already done since Flips post talked about mediation with a 3rd party (which would be a rather unusual reaction for 2 people being toxic to each other) and we wont hear any more from Riot
