It's not that they didn't warn bluesky specifically. It's that they didn't warn relay operators in general. And IIRC they just needed to coordinate with a single relay operator who is reasonably trusted (ex blacksky or eurosky) but they didn't do that either.

The default rate limits are quite reasonable but big launches will blow past them so you gotta coordinate with someone.

And note that the relay federation/gossip agreements are largely manual configuration at the moment. Until someone pushes a proposal for an automated/dynamic topology management algorithm that doesn't get plagued with spam issues it'll stay this way.

No such problem on Mastodon/ActivityPub.

[OneDeuxTriSeiGo]

It absolutely is. Mastodon has rate limits and administrators have to manage and adjust them as necessary for their instances.

You probably just don't notice it as a user or as the operator of a small instance which to be fair is exactly the same with atproto. Users rarely notice rate limits and small operators rarely do either. It's the operators of large services that see these limits and have to coordinate with other operators.

The issue with W social is that they have a chronic inability to coordinate or play nice with anyone else in the atproto space. Rate limits aren't a problem if you are a good neighbor and you know your neighbors but frankly they just don't.

My Mastodon instance blocked Threads preemptively because they were afraid of the traffic driving up their hosting costs so you’re basically just very wrong or lying about this. A huge flood of incoming traffic can be hugely expensive for ActivityPub node operators. The problem of giant onboarding events is real, there’s just no default protection against them in Mastodon like there is in Bluesky, so operators either have to take matters into their own hands with defederation or risk driving their bill through the roof.
