I just saw an entire train of spam from a commenter that appears to be dealing with ... a lot. I'm not naming names, but suffice to say there are definitely some folks dealing with mental issues posting the way being described here.
Still, that isn't the norm. It probably just feels like more because this is such a small space - when there aren't hundreds of comments (like found on more popular social media sites), a few spam posts can feel like a lot.
Maybe it's because I like to focus on the positives, I still think there's more quality content here (by percentage of overall comments) than on many other sites. There's a lot more thoughtfulness, and more people resolving disagreements by actually listening to each other and seeing each other's sides. I've been reading Lemmy since leaving Reddit during the API debacle, and I've noticed I feel much better about engaging in the community here than I ever did there. I've seen countless Reddit arguments that hinge on one (or more) stubborn parties refusing to take in new information. I used to feel dread when I saw messages in my inbox, because no matter how carefully you tried to word your thoughts, there would invariably be some troll intent on misunderstanding your comment at all costs. It was exhausting and discouraging.
I realized recently that I no longer feel that way when I get a response on Lemmy. I mean, I still approach clicking that box with a tiny bit of trepidation, but the more I click it, the more I see rational responses, funny commentary, and simply friendly people responding in light conversation. There are trolls out there, but I've come back to see responses already deleted by mods, and other commenters defending my position, all without me knowing what the troll even said. Despite all Lemmy's flaws, there are a lot of decent people here, and it seems we look out for each other.
We must continue to practice this rationality and kindness, and encourage new-comers to leave their Reddit life at the door. If we want Lemmy to be better, then it's on us, its users, to build and maintain the culture we want it to have.
For me, I like the peace. Pass it on ✌️
We're Lemmy. The best we can give is the hug of coma.
