Fediverse

There's nothing stopping them from hosting a massive instance. But people aren't forced to move there to interact with them.

If another instance started knowingly federating us ads, or fake content, I'd hit that defederate button very quick.

Nothing. Instances will have to take it upon themselves to defederate, just like how a lot of instances all decided to defederate from Threads.

Nothing, but instances can defed from them if they wish and they can't stop that either.

What is stopping corpos from scraping everyone's posts and stuff from the fediverse and train their AI?

Nothing. And they already have.

What's stopping them then, to create loads of not accounts and spam / disrupt smaller communities?

Moderation.

When an instances quality drops, the users may be more incentivised to migrate to bigger instances and go there.

Why would they do that when every instance has the same content?

Corpos can flood the fediverse with ads

I mean they can but no one would subscribe to them or share them, so no one would see them, so why would they bother making them?

about how certain countries behave. I feel the true evil are the corporates.

Sometimes the two are actually one in the same.

Thankfully, there aren't any ads here. Just the thought of it stresses me out, and when I get stressed out, I reach for a Morley cigarette to keep my cool. The toasted tobacco and asbestos filter make for a smoother smoke, which soothes the throat. 9 out of 10 anti-ad, Fediverse, activists choose Morleys to keep up their pep and vigor in the fight against advertisement.

That very real and enforceable "this comment cannot be used to train AI" crap some people add to every comment that definitely makes bots not scrape the comment, of course!

The fact that corporations sees the fediverse as inconsequential. The minute people flood it in larger numbers as they are fleeing the corporate entshittified internet, that is exactly what they are going to do though.

1. Disruption: Probably ethics? I mean, I know big global businesses barely have any, but they do care about their reputation somewhat. Anyone running a botnet to destroy small/medium fediverse servers would be discovered fairly quickly, I suspect. Nothing is going to stop AI training scraping outside of regulation, I suspect.

2. Ads are enshittification. Federation is defense against it, because it prevents vendor lock-in and allows migration while maintaining your network effect. Threads already tried to join, and nearly nothing of theirs gets through. I'm on a mainstream mastodon service that doesn't block threads, and I've seen a threads post only once or twice. Threads can't display their add on my service, so there's no incentive for them to push content.

We just defederate.

Nothing stops them right now. Currently they're causing effective DDOS by scraping manually and there's no good way to block them except by going to extremes.

In fact, I would prefer if they just used their own instance to scrape content instead of causing downtimes like they do now.

Corpos can flood the fediverse with ads and crap:

For that, the solution is simple, we can defederate.

Facebook tried and we scoffed.

It's called the Embrace, Extend, Extinguish strategy of dealing with threats. Microsoft have been endorsing Linux recently for this reason.

We would find out. We would defederate them

Lack of interest from their part. Right now, they have nothing to gain, fediverse is "small fry", and if the attacks could be traced back to them, they'd have to deal with the PR shitstorm

They're probably already doing that

They are already training on the fediverse. If something is on the public web, you can assume it's in some training data somewhere

1 - You can block/ignore entire instances. (spamming ones)

2 - If it gets big enough, you'll see legit instances band together and federate only among themselves (white-list, invite only to allow federation)

people will gravitate to these groups of instances if they are well moderated and keep that crap out.

Nothing

You can defederate from the corporate servers.

There's no economical incentive to join the fediverse for large corporations - at least not yet. I think it'll take another 5 years before that happens.

The !boycottusa@lemmy.ca and !buyeuropea@feddit.uk movements would have to become mainstream first, because let's be honest, the fediverse is the actual contender to US social media. Although, right now it's really fediverse vs bluesky. Once someone creates a reddit clone on top of bluesky, then the fediverse will lose that battle, because people are uncomfortable with choice.

Everything posted on the public web is potential AI training data, federation is completely irrelevant to that.

The rest of your questions has the simple answer that a priori there is nothing "stopping" any of that. You should choose an instance whose admins are looking out for things like that and keeping your experience enjoyable, banning spambots or defederating from spambot farms when they are discovered.
