Agreed, for sure. If anything, decentralization makes those things harder, I’d say. And also agreed that there are benefits to decentralization along the lines you mention. Those two things can be true at the same time.
I think it’d be cool to figure out what the toolset to handle those issues is before they become a problem. Or, honestly, just because figure it out would be a meaningful challenge and may move the sorry state of social media in the right direction just in general. That said, there is a LOT of overcomplacent assumptions, at least in the userbase, regarding decentralization being a magic bullet. I think the development side is a lot less… I don’t want to say naive, but a lot more realistic about the challenges, in any case.
I am old enough to remember that IRC had more in common with 4chan than modern social media and that moderation of atomized, non-interoperable forums was either just as bad or handled at much smaller scales by people with commercial interests.
You care about how many bad actors there are if they are enough to be in every instance. Again, you’re presuming that bad actors will choose a specific instance to populate. You can’t defederate from every instance that allows people to sign up or you end up with a group chat instead of a social network.
That’s the Fedi-wide problem to solve if it ever gets truly popular. If I put together a bot farm or a sweatshop tomorrow that targets every instance of every Fedi app with multiple spam signups per minute how would you stop that? Especially if I’m not immediately posting spam and instead generating bad content slowly over time.
What if instead of one person doing it it was thousands? How high are the garden walls at that point? Is there anybody left inside them?
“There are tools to do that” is a bold assertion, but nobody has been able to explain to me what those tools are or how they’d work at scale. I’m all ears. Even if I don’t think it’ll be needed I’d love to know what the plan is, if there is one.
