qoto.org bad/spam actors

It seems like some bad/spam actors are spamming requests pretending (?) to be actors from qoto.org (redirects to social.cleverlibre.org) all from various different IP addresses. Luckily that instance is offline (?) so none of the spam is getting through to me because I can’t look up the actors, but it does mean my site is making requests denied by 406 and some 403 denied with a HTML response. I set an instance block on qoto.org for now to prevent any more additional lookups.
