Selfish leagues admins

There is so many leagues admins who is so much selfish they build a league and they waited until it becomes big and have a big level then they removed everybody just to get all the rewards for themselves. I saw many posts on social media before complaining about it but today it happened to me i was the 5th in my league and a friend of mine was the first and the admin wasn't even from the top 20 he wasn't playing that much and he removed us all to get all the rewards for himself alone.

This problem need to be fixed maybe stop admins from removing people in the last week or if someone got removed they can get the same amount of rewards Which was recorded as what he would get before he was removed from the league.
