Perhaps? Honestly don’t know and don’t care. Downvotes mean nothing, just fake* internet points and I heard that down/up votes don’t mean the same thing as on Reddit.

No I'm not because karma doesn't affect your account on Lemmy as it would on Reddit. I can still say and do whatever I want with no restriction because my account isn't tied to karma. Like if I had been downvoted enough, posting would be a pain because of karma limits. But, I'm not weighed down by that so downvotes don't really affect me.

What it does tell me, is just there being a group of spiteful people, presumably from Reddit and maybe a of Lemmy's own. That just have too much time on their hands and again, are toxic people who refuse to see that they themselves are what's toxic but they love to put the blame on anyone else.

I have seen power-mods (like on reddit) who will delete any comment that they deem "off-topic," but no trolls that downvote. Do you have an example?

No.

No matter where you go, upvotes and downvotes are still subject to the Lizardman's Constant. Someone will end up voting in a totally contrary way just to be contrary, or because they didn't understand, or because they just hit the wrong button. No matter how great your content is, it would be weird and possibly suspicious if it didn't get some downvotes.
