While reviewing some of my suspected users, I found submissions of Js1.

If we closely at this guy's previous contest submissions: https://codeforces.me/submissions/Js1

We can easily deduct the following points:

• He has changed his template 3 times (specially from B to C problem), in the 3 problems he solved,

• In one of his previous contest, all of his submissions were skipped,

• And all of his submissions were AC in one go, which clearly shows how desperate he was (like other cheaters).

It is near-to-impossible for MOSS to detect these kind of cheaters, so I request MikeMirzayanov to take some action (again as in that previous contest) over it. And also, needless to say, thanks for giving us such a great platform like Codeforces.

You da bestt!! <3
