Ok, I retract what I said earlier about this player being banned. I did a little more research, since I was just going off a post on another forum. Supposedly this player was banned December 23rd 2011, and the post linked to a Riot post, but it had no mention of the player being banned at all, only temporarily suspended. Furthermore, this player has appeared in tournaments as recent as December 2012, so apparently he has not been banned permanently, and the "has been suspended numerous times" thing still stands.
And I suppose it doesn't hurt to say the persons name; I'm talking about saintvicious.
Can someone confirm/deny this ban?
Ultimately, if this player is still allowed to roam free, despite being a "toxic player", then I really see no reason why many of the currently permabanned players (on the 3 strike rule) need stay that way. It's unfair to a vast majority of people who may have done wrong in the past and are currently paying for it. They should be given a reprieve at the least, so they are given the chance to reform in the present knowing that they can be permabanned for their actions.
