Aren’t lemming, fedizens, and reddit r/efugees referring to different specific groups of people?
It might be best to go with something that has more appeal. That’s part of why I went with lemon because it seemed catchy. Lemmings, unfortunately, has historically had a negative meaning. Fedizens is okay, but citizen might be better as it isn’t a portmaneau (new word combined from other words)
This is normal from ram caching. If you get sudden slowdowns and run out of free memory, then you should become concerned.
