Just a few years ago, you would never see such a disparity in votes vs comments. But these days, this is pretty much the norm. I've seen posts with 10K+ upvotes and no more than 80 comments.
I'd say in about 2 years, the entire place is going to be bots with AI generated content that try to mimic "real users" using their new Dynamic Product Ads tool. Not sure how that's legal as I thought ads needed to be marked or differentiated from regular content, but here we are.
The future looks bleak and AI even bleaker. Because it's going to be used against us to make the rich richer and not to make our lives better.
I'm fuzzy on the details, but I do get reports from users on another instance as long as it's "relevant" (ex. in one of our communities, one of our users)
Banning a foreign user on our instance will fix the problem for our instance, but they need to be banned on the home instance too in order to stop the spam from continuing
Does ActivityPub report back bans to the user's home instance? I could see a moderation tool that let the admin autoban their users if enough federated instances had banned them.
