To all Mastodon-admins: seems like there's an attack on all instances by troll accounts. Servers get slow because of it.
They use thousands of subdomains of activitypub-troll.cf. My 'pull' queues skyrocketed.

I now blocked the domain activitypub-troll.cf and all is back to normal. Please check if you're hit too.

In fact this is a good sign.
Someone is afraid of us!
@Fogomet @ruud -- The more popular Mastodon becomes, the more sophisticated the attacks will get. But the decentralization perhaps will make it easier to deal with such sabotage.
@floh @ruud
Right.
Anyway decentralization is a strong point because it is very difficult to buy Mastodon.
