Suspected cheater : smajumder99

This guy's real name is Sabyasachi Majumdar. He studies at Jadavpur University in India. Even three days back, he was able to solve only 3 problems in Codeforces Round 1108 (Div. 2) contest. But yesterday he AKed Codeforces Round 1109 (Div. 3) contest, solving 7/7, within an hour. Not only did he cheat, but he is also shamelessly posting his contest performance on LinkedIn. Please look into this matter. MikeMirzayanov
