There's some misinformation floating around regarding Lemmy not having a karma system. While many have discovered otherwise, this is for those who may not have.
While it's not exposed in the Lemmy default user interface, Lemmy does have a fully functional karma system and it is visible in third party clients such as WefWef and Memmy.
I think that is too idealistic. It could very easily go into a downward spiral that a community could never get out of. It happens already on several subreddits already. You may not have experienced it, but I can say it for certain happens. There have even been scifi series written about it that have taken the concept to the extreme.
I’m familiar with some of the subreddits, but I believe you’re taking the spiral too steeply and too quickly.
The “don’t be a dick” philosophy will get you more than enough karma to comment on whatever subreddit you want to participate in, outside of some super niche ones.
I really don't think you do, you are being incredibly closed minded and sticking your head in the sand. Because it has no* effect on you (yet).
That is a bold assumption to make. I’ve absolutely been affected by it on Reddit, and I’ve been banned from subreddits from saying the “wrong” things. Hell, I’m a lesbian who was banned from r/ActualLesbians because I said lesbians are attracted to women and not non-men.
