It would be fair tbh.
Why would a bad behavior previous from 22/08/17 be any different from one prior to it? Both have had bad behaviors, and surelly both situations are trying to improve. Nobody is perfect, neither you Riot, and in my personal point of view i consider this very unfair and none sense. This is like having a free pass to commit murderer in some stage of the year and dont have to worry about it, because in the end of the day instead of going for jail you would be rewarded.
Be coherent Riot.
