Boosting

As we all know boosting accounts is still a problem that riot does their best to handle but they only consider it "boosting" if someone gets onto an account that they don't own in fact the only real reason riot has a problem with boosting is account sharing that's the only thing they care about but I think that boosting should also be someone playing on a smurf and duoing with a lower elo player I understand this may be hard to combat but it's not fair to the competitive integrity of the game and some may say "Well if they play more games in that elo they will fall out of it" but they don't have to play more games all they have to do is sit on the rank and play one game once a month as to not decay it also makes it unfair to the people that have to play with the boosted player when they get to the desired rank since they shouldn't be in that elo they will make mistake that higher elo players can capitalize on it puts the people playing with the boosted player in an unfair position that they can't do much about I'd like to hear the rest of the community's thoughts on this
