Def some better than others. I give them props because looking through the modlog, they are good at removing or banning trolls, bigots, and far right disinfo. I just personally disagree with the seemingly frequent support for Russia, China, North Korea, etc.
At least in memes, politics isn’t the focus of the community.
I haven’t looked into it too much or done it myself, but I heard of https://creativeheartwarrior.com/pages/filament-recycling
Looks like they currently only take filament as a donation and not as an exchange.
Edit: also found https://printeriordesigns.com/pages/recycling
(Again, haven’t personally tried)
