I'm Getting Warnings For Negative Attitude For No Reason

Hey guys, I play League of Legends from Season 1 and I never got reported or banned before. Today (7/9/2015) after the ending my games I'm getting warnings for getting reported for negative attitude. The weird thing is that I didn't chat, troll, flamed on the games .... Can it be a riot's bug ? Thanks =) _R.I.P Riot_

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
