Is it spam, or is it literally just people using the fediverse as intended, coincidentally in a language you don't speak? Folks who speak a language other than english aren't less welcome in the fediverse.

If it's an issue because it's drowning out all the stuff you can read and engage with, I think you can set a Mastodon account so you only see posts in a certain language. Other platforms may have similar settings

If it randomly mentions other users, and if it comes in such masses that Mastodon admins have to raise the shields and Fediblock the hell out of dozens of instances, then it's spam all right.

That said, the last spam wave was organised on Misskey again, but carried out by bots from Mastodon instances largely abandoned by their admins. At least partially, this was the case for the first big spam wave as well.

Is there a reason why miskey users organized a distributed spam wave from Mastodon...?

But yeah, miskey is much more popular in Japan, whereas here in the west Mastodon is much more popular

I recall it was just student that do script attack.

Some Misskey instance like Misskey.design, Misskey.io, and Misskey.id also got their attack several months ago.

It even reach mainstream news outlet: https://techcrunch.com/2024/02/20/spam-attack-on-twitter-x-rival-mastodon-highlights-fediverse-vulnerabilities/

Ah, gotcha. Thank you for the additional information :)

It's spam. Most Fediverse software like Mastodon and Pleroma support MRFs that protect against spam, as I understand it, but Misskey doesn't. And since Misskey users are mostly Japanese, so is that spam, as it's targeting that Japanese audience.

Interesting, thank you for expanding on how the spam issue has happened.

I'd not heard of MRFs before, from some searching around it would seem its a Markov Random Field model (in case anyone sees this and also didn't know what it was)
