How does Riot detect MMR boosting?
I am really curious as I see a lot of people posting about being baned for that reason, more than ever. I know its obvious that someone is being MMR boosted if he gets an insane spike in win rates or if summoners are all of a sudden placed on a different key but what about personal habits of a player? For example, I mostly play normal games with my friends until they go to sleep and than I go play few ranked games but what is gonna happen if I cecide to focus on ranked games when season 8 starts? Is Riot going to detect it as MMR boosting or account sharing because I am not playing normal drafts anymore? I mean, I really don't want to play normal games just to keep my current habits on point in order to nit get detected for "weird behaviour on my acc.
Sorry this may be a stupid question but I have no idea how that thing works as I have never been restricted for anything since day one (season3), never inted, never trolled, never flamed or used a bad word, never shared my account with anyone and never chat restricted.
Enlighten me please. ^_^
