yeah i have been there, here is some reasons why
1 its because chess.com has more cheaters than lichess
2 after u win your first game on lichess, you will get like 600 elo or more in your first game, the elo you receive will eventfully get lower cuz you will start playing more games
3 its because of the pre-move delay on chess.com
hope this helped
Here we go again...
Chess rating is relative and depends on a community you play in
Chess.com has larger community than lichess which leads to higher number of lower rated players, and in general the higher your chess skill the smaller the difference between ratings on both platfoms
Chess.com and lichess have different systems to measure the rating: Gliko 1 (chess.com) and Gliko 2 (lichess), with the lowest rating of 100 on chess.com and 400 or 600 (I dont remember exactly) on lichess
I too, love to spread misinformation on the internet
My bullet rating on chesscom is 1400 (just reached) but my lichess bullet rating is 1900. I know there is a ⁓200 point difference, but this seems weird.
