Comparing the time when I joined Lemmy around 2 years ago to now, I would say that the general tone has become somewhat more unfriendly. A larger userbase might be a contributing factor, but I think it’s also the political climate in the west becoming a lot worse recently with many divisive issues and people being more stressed about the state of the world.
In general, no.
Depending on the situation, as a last resort, yes.
