Yep, those on top100 at midnight EST on Nov 30th will get their medals and all accounts will be reset to $1500.
BTW, competition for top100 gets very intense in the last 24 hours. Additionally, a lot of people chip dump to their friends or to their other accounts to ensure they get medals.
Last month I drifted out from 76th to 99th in the last 24 hours without playing a hand. So do not think thay sitting in 88th now with £706K will get you a medal, it may but it may not.

true, i stopped at a million $ at 55th place, but checked my medal, and its 74th

odnexa, same I stopped a week from the end at $1 million and drifted out to 75th in last 24 hours.
It's because a lot of people chip dump to friends or combine accounts.

This is obviously cheating and very annoying but I have no idea how it could be stopped.

I am sure some people have 10+ accounts and play like maniacs, a few lucky flops here and there and they can put a stack of chips into one account having played like idiots.

I could name some of them but will stay quiet on that.
