Hii This guy named EvilMorgana obfuscated all his submissions. For example https://codeforces.net/contest/1312/submission/72833573 His previous 2 accounts were banned due to this and he is repeating this. His previous accounts are buihoatpt2k3provip buihoatpt2k3 Same thing happened there. For example https://codeforces.net/contest/1305/submission/72346939 https://codeforces.net/contest/1305/submission/72343779 Do check this once and take action plsss
