First Day on PBE and...

I saw so many toxic player that I don't know how they get the access to PBE. They think only to win the game, and if you are playing bad they start flaming and report at the end of the match. Now, I would like to know who admitted these people here. Isn't our duty to report bugs and other things? Why should I always get insulted by those brainless? Please Riot, be careful next time.
