Hi everyone. I just wanted to ask whether the average strength of lichess is going up yet the ratings are deflated or it is simply a glitch in my performance. Look at this tourney
en.lichess.org/tournament/6CVU4KA0Here even 1600s and 1700s were playing really well, and it was very tough for me to defeat them. A year back, however, it was very easy for me to defeat a 1900. It looks like everyone under 1800 is 200 points underrated.

The average strength of lichess going up and ratings deflating are not contradictory at all: it just makes sense.
If ten players FIDE rated 1200 use the Glicko2 system to rate matches between each other, the average would be 1500.
Now, if ten players FIDE rated 2600 would join that same pool, the average would remain 1500, meaning the rating of the lower rated would go down a lot.
So, if the average strength of a player pool increases, the ratings of players will go down and vice versa. I think that's what might be happening to lichess at the moment.

strong players are migrating from
chess.com because lichess offers so much premium stuff for free, mabye?
Think all commercial server owners are raging because of Lichess. A fine sum of money they don't collect. Actually I paid my duties on other servers but many won't. And will I do so in future? Time will tell!
I don't commercial servers really care about lichess. It is still way smaller than
chess.com and ICC tends to get the 'establishment'
as to opening of thread. Obviously ratings deflate if average skill of the pool goes up. But to measure it there should be some centipawns/move measure implemented for different rating categories and see if there is actually deflation.
#1 Supposing you are correct, it is equally possible that tomorrow thousands of beginners (or experts) join lichess and ratings slightly inflate (or decrease). But that seems unlikely when you consider how Glicko-2 works:
