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.
