You have to walk on egg shells now. rito is very trigger happy when it comes to dealing out final bans. Basically, if you are even slightly negative (saying something like "gg ez" or "ff at 20" or "game's so over" or "report xxx for toxic"), even if it's just one line 5 minutes into a long game that you end up winning, and someone on the other team reports you because they're salty, you will probably get banned.
There is a certain subset of rito white knights on these boards that love to say "false reports don't do shit, blah blah blah.." in posts like this. But if you look a couple posts down, you'll see instances where people have been perma-banned after games of slightly negative speech because angry teammates reported them out of spite. Those same people will then say "well, this game might not have been so bad, but they don't ban you because of one game they ban you after a bunch of games!" They aren't consistent in their arguments across individual posts except in that they will always try to justify rito's actions.
