Boosting companies what needs to be done

what do you think about all these stupid boosters that are ruining the game for people gold or higher who worked to get there and what can riot do to stop this boosting? We have players in Diamond who are really Bronze V players but want to take short cuts something needs to be done because you have people getting possibly scammed or just wasting money to go into a division they don't belong in. I have seen this a ton and it's just flat out wrong in so many ways
