There was an incident on lemmy.world that has had an impact on other Lemmy Instances. Some malicious users or bots posted illegal content, specifically CSAM, to the lemmy.world shitposting community. The administrators responded promptly by shutting down the community and changing the registration process to application forms that require manual approval.

The administrators of lemmy instances and those who self-host lemmy Instances have been advised to clear their cache from the past 24 hours. This will help to remove any potentially cached content.
