i have noticed something weird in the standings of Codeforces Round 992 (Div. 2)(and probably some other ones), if you go to the standings you can see the person who got rank 1 is daniel6202, which AK'ed the contest as an unrated which is suspicious but that is not the full reason, if you go to the account you can see that the user is disabled, and if you go to the contest page, you can see that the user only attended two contests one which was Codeforces Round 992 (Div. 2), and the other Codeforces Round 993 (Div. 4), in the second contest he had all of his submissions skipped, which means probably he cheated, but how can an unrated user, fully AK a div2 contest (he was the only one which fully solved the contest and solved a 2700 rated problem in about 12 minute difference with the last problem which he solved) but get caught cheating in a div4 contest. and after the user is disabled, it is still presented in the standings.

UPD : there are obviously alot more like lequoctran181 which you can read more about him here, but got high ranks in Codeforces Round 1007 (Div. 2),Educational Codeforces Round 174 (Rated for Div. 2),Educational Codeforces Round 172 (Rated for Div. 2),Codeforces Round 984 (Div. 3),... and isn't getting removed from the standing
