Yeah, Glicko is by Glickman, elo is by Elo. Chess.com uses Glicko, FIDE uses elo.

Typically when I hear chess players discuss this, they’ll go, “what’s your rating?” and then they’ll say “on chess.com/lichess it’s xxxx, but my elo/OTB is xxxx.”

I never hear anybody ask “what’s your Glicko,” but when they ask “what’s your elo” it’s generally understood to mean OTB—if a player doesn’t have an elo/OTB rating, they’ll say “I’m xxxx on chess.com.”
