I think Nikesh.s is using a bug which shows him online inspite he is offline. When i m clicking over his name in the ppl window, the page not found. Also, he is not visible in the online players list while i m in a game with him. PLZ CHECK THIS: lichess.org/a9gprcom
The problem with his name is that he is using a dot in it ( Nikesh.s ). http protocol thinks it is a subdomain and tries to point to it ( like .com, .eu, .co.uk, etc ). This happens to everyone having a dot in their names.
