about extreme Friendica servers load some admins lately complained.
very possible some other Fediverse servers may also fall into this malicious trap.

I discovered there's a malicious pseudo-server malware that makes Friendica perform endless GServer updates: it creates a multitudes of faked *.activitypub-troll.cf domains that are all NXDOMAIN, shoves them into some posts (I didn't trace down how they got into the list of Fediverse domains) and Friendica tries them all, creates thousands of tasks and wastes a lot of resources.

to avoid this, ban domain by mask:
*.activitypub-troll.cf
then run on DB the request:
delete from workerqueue where parameter like "%.activitypub-troll.cf%";
