Tried mastadon before moving to Lemmy. I ended up leaving mastadon as I didn't find that the voting system allowed me to not only read the individual, but also the mass. Lemmy does this much better.
But I do feel that the lack of karma is nice, no reason to be dragged down by your previous bad decisions, or masses who don't understand your humor.
Oh, and I guess it's nice that one can turn off the votes if they don't like them. It makes for a better experience for a broader set of people. But I feel that turning off the comments votes (derp) by default, or perhaps disabling them entirely, would turn Lemmy into nothing more than a glorified RSS feed - which isn't exactly bad, but not the reason I'm here.
I don't see that setting on my end. I don't think I'd want it off, but if having a switch option makes life better for some people I don't see a problem with it
You can't always trust that the mods will - or even can - take any action, though. Especially due to the federated nature of things.
For instance, you and I are both commenting from different instances, on a post made on a third instance, by a user from a fourth instance. Who has power over who in this situation? Between you, me, and OP, none of us "belong" to the instance this thread is in. Who are the three of us supposed to be trusting to keep this place clean of that sort of content?
One could argue that that's just the inherent risk you take in using federated platforms, but I don't think that's too widely understood among the user base at large just yet. A simple user-maintained scoring system, even as rudimentary as Lemmy's implementation currently is, does a lot of heavy lifting in regards to filtering the good content from the bad.
