It is very interesting to me, after browsing the boards for as long as I have you start to notice the same thing said over and over in these posts.
The thing that I see over and over is when people say that Riot bans people for not doing anything wrong and doesn't ban people who do things wrong.
It is a completely baseless "argument" that is put forth, and I feel as though people don't realize that when someone is banned, it is not without good reason. Some people do not realize that when they agreed to Riot's TOS (Terms of Service) they have to abide by those terms, there is no exception to that. When people decide to retaliate toxicity with their own, they are just as at fault as the person who started it.
