Right now there are people who sign up with an instance like lemmy.world, who then create loads of communities, because they don’t fully understand the nature of things and can’t quite believe that the URLs for lots of different IPs are available. For Reddit, if you snagged the likes of r/starwars early on, that gave you some power. For Lemmy, it’s meaningless: if you just want to moderate 100 communities, and not spend time actually building a Community up, then you’ll just be overtaken by the Community at one of the many other instances.
It’s probably whatever my phone charger uses (USB C probably), but that’s mostly because I’m associating the little buzz my phone does when it starts charging with the connection. So yeah, purely fetishistic.
There was a point (only a few days ago really) when browsing All was a way of discovering new communities, but now, if it’s not memes it’s auto-generated bot content harvesting link from HN or wherever.
Everyone became convinced that ‘old memes’ were the new thing (possibly in response to the popularity of Antique Memes Roadshow) and they swamped out everything else on All
Just start one (a community, that is). There’s not some marauding band of trolls out there, waiting to give you a hard time. If it’s niche enough, it’ll be a highlight just to see someone-who-isn’t-you post something!
Follow the link from the LinkFixerBot so it’ll load that community whilst keeping you logged in on your instance, and you’ll see a big “Subscribe” button.
For any weird, bigoted stuff, lots of downvotes and no replies is hopefully the message an OP needs to receive to get the hint that they should by plying their recruitment attempts elsewhere. Engaging them is probably the worst thing to do.
I’ve had to remember that there’s automatic hiding though, and do that manually.
