please do something about boosters in rank...

One of my friend admittedly told me he has his diamond friend playing on his account, and right now hes getting boosted from gold V to plat V as we speak... he is picking each and every different champions, and doing non meta builds with roles played in them....

I mean.. I know people can hate me for being a "snitch" but this is just disgusting, despite that he is my friend.

Boosters are ruining this game... seriously.. this is not fun anymore to everyone in rank....

Its been 6-7 years and Riot still hasn't done this as if the replay system that they are FINALLY going to bring in soon after 6-7 years later wasnt laughable enough while games like starcraft in the 90s has its own replay system....

No one deserves to get boosted to a rank that they didnt not earn my themselves....
