3 so far.. but it's mainly trial and error.
Started off with Lemmy.ml then wanted a bigger instance.
Moved to Lemmy.world then ended up having too many users and lagging.
So I moved to a good compromise: Lemmy.blahaj.zone
But yeah. Three so far with the exact same username ๐ฌ
I usually play Blockudoku or Card Guardians for HOURS.
I've also been binging mahnwas and occasionally scrolling Lemmy.
