hello. Real question. its few days b4 end of season. usually at the morning b4 work i play fine. at the night some times i feed alot not init just drink smoke)) so no joke, if i will get in high wRatio couse i realy want plat. i have to be afraid of "boost ban". irealy afraid . i read here alot of peoples say its not true no boost ... but who knows maybe some of them realy not boosted.

Again if i get into win streak/WR increase did it will triger riot?
