Lets START PERMA BANNING troll teams!

I just got trolled again by 4 premade team. started the que with them telling me "you going to lose" and saying other stupid things like "have our babies". I couldn't leave the que since i would have been suspended since dodging que even though you have an obvious troll team would mean RIOT would punish me for it (RIOT is terrible managing this issue FYI). Some games are abled to be salvaged when u have 1 troll, but against a team that chose to troll right from the beginning is down right impossible. MAYBE ITS TIME TO BAN ACCOUNTS PERMANENTLY LIKE SOME RESPECTABLE COMPANIES ARE DOING!!! OR IS RIOT WORRIED ABOUT LOSING $$$$$ FROM THESE SCORNS OF THE GAME!!!
