I believe it was a mistake that I didn't notice it was a 4th ban that I have made on him, it should've been a permanent. I do believe that redchecks should not lift this ban and keep this permanent, 3 ban is enough to give you a warning before you get permanently banned.
But that is not make decision to make, please wait for him to respond.
By the way, please remove the poll, it isn't necessary.
