While reviewing some of my suspected users, I found submissions of Js1.
If we closely at this guy's previous contest submissions: https://codeforces.com/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
