Hello everyone! I'd like to bring the community and platform coordinators' attention to the account of user levsivko. In just 5 rounds, this participant shot to the top and achieved a rating of 1508, earning the status of "Specialist." At first glance, this seems like a great start for a talented newcomer. But if you open his contest history and look at the results tables, you'll see a classic, stupid, and completely shameless timeline of buying solutions from Telegram channels or using third-party help. This account's behavior completely contradicts any human logic for solving Olympiad problems. Let's examine all of his "achievements" step by step.

Evidence 1. Educational Round 192 (Div. 2) — A classic "failure" of Problem B after failing A. Look at his results in Ed. 192: Problem A: Complete failure. The participant makes one attempt, receives a Wrong Answer (-1), and completely abandons the problem without even trying to fix it. Problem B: Successful submission (+) at 68 minutes into the contest on the first try. Why this is plagiarism: Problem A in Div. 2 is a very simple ad-hoc logic problem requiring basic knowledge of the language and conditions. If a person is unable to find the error in A, they are physically and mentally incapable of solving the much more complex Problem B right away. The explanation here is trivial: the "help" groups delayed the code for A, but sent a ready-made solution for B in time. Lev simply copied someone else's code, not even understanding how to solve the first problem.

Evidence 2. Codeforces Round 1109 (Div. 3) — When the "helper" did not respond. In Div. 3, we see the perfect marker for a "purchased" or slave account: 0 solved problems, 0 attempts. A completely empty line in the results table. Why this is plagiarism: For a real "Specialist" with a rating of 1508, problems A, B, and C in Div. 3 are an easy warm-up lasting 15 minutes at most. The fact that he registered, entered the contest, officially opened it, but didn't make a single attempt to submit even the simplest A proves only one thing: the code leakers disappeared from the network that day (or the round coincided with a strict anti-plagiarism check), and Lev himself is incapable of writing the simplest cycle without someone else's guidance.

Evidence 3. Codeforces Round 1111 (Div. 2) — A magical rise to D1 level problems, of course, after a shameful zero in the easy Div. 3, the next round of Div. 2: Problems submitted: A, B, C, D1. Almost 3000 points in the table and top place in the round. Why this is plagiarism: A person who just one round ago was sitting with an absolute zero in Div. 3, suddenly, without a single mistake, without penalties or false attempts, is solving problems C and D1 in the difficult Div. 2. Such a contrast in training and skills is physically impossible. Obviously, this time the code pack was purchased or received in advance and submitted strictly according to the timings. Evidence 4. Codeforces Round 1112 (Div. 2) — The Apotheosis of Impudence: Submitting the extremely difficult F instead of D and E. While the cheater could still try to attribute previous rounds to "chance" or "mood," this contest is a complete self-inflicted blow. Look at his line: Submitted problems: A, B, C... and suddenly F! Problems D and E: Completely skipped, not a single attempt. Why is this cast-iron plagiarism? An abnormal jump in difficulty. Just look at the round statistics: problem D was solved by 2609 people, while the extremely difficult problem F was solved by only 332 people on the entire platform! The logic behind scoring. No honest participant capable of independently solving the cumbersome or mathematically complex problem F would ignore the much simpler and very "high-scoring" problems D and E. This only happens in one case: the completed code for problem F was leaked into a private channel (for example, one of the top participants shared the solution in a closed circle, from where it was leaked). Lev, completely ignoring the consequences and the risk of being caught, simply copied it and sent it to boost his rating.

Bottom Line: This is a classic, blatant example of rating manipulation through plagiarism and solution buying. The participant is completely unconcerned about secrecy, submitting problems backwards and jumping from absolute zero to solving grandmaster-level problems in a single day. I encourage the community to take a look at his solutions to Problem B (from Ed. 192) and Problems C, D1, and F (from recent rounds) – you'll likely find 100% matches in structure, variable names, and logic with other accounts using the same sources. I hope Codeforces coordinators (MikeMirzayanov) will take notice of this profile and conduct a standard plagiarism check followed by a ban or rating reset. Cheaters have no place at the top! If he gets 10 likes, we'll make a new expose.
