There's close to 30.000 communities on the Lemmyverse, most of them on servers/instances different than yours. You're on lemmy.world, one of the most "general" instances that took on a lot of the migrating users so there's going to be a more "reddit" style userbase there.
Check out https://lemmyverse.net/communities and look for other communities for your favorite topics. I'm sure you'll find different communities with different type of users. For instance, I browse !technology from several instances. Many of those communities I don't bother commenting in, simply because it's not my crowd. If there's a good post I want to discuss with likeminded people, there's always the cross-post function.
Checking post histories and holding it against users, presenting Lemmy as "a site" instead of interoperating and independent instances where one can tailor ones experience, not advocating finding more suitable communities...
Very reddit behaviour to my eyes.
Fuck everyone, people suck no matter what platform one's one. But the main idea behind the fediverse is "make your own".
Block people whose replies are of no value to you. Block communities that harp on about things you find annoying. If you find anonymous downvotes instead of proper replies cowardly, go to an instance that doesn't accept downvotes.
I'm having a great time on Lemmy.
There's always Peertube's "channel sync" which does pretty much what you describes.

Only thing is that it's public sharing so you'd have to find ways of locking it down if you want a private server.
Grisly robot injuries?!
Like bear robot or regular robots, just gravely wounded?
I used to be a region hose down emergency worker, we're the people you call if employees refuses to be hosed down. AMA.
