I believe we're compliant with the law, I've patched our Lemmy with this so we're not hosting NSFW content and to my knowledge we don't have any communities that need to be age kept (ones that encourage eating disorders, suicide, or self-harm). I think we need to make some changes to our TOC and land some documentation explaining how the report feature works 'in a way that a child can understand'*. There are more changes I'm looking at making in Lemmy that would make Ofcom happier (like this), but again I don't think we'd have issues with Ofcom if they looked at us.

* We have to assume you're all children as we can't say otherwise unless we do surveillance (or 'age verification') despite the average age of users of this instance probably being in the 30s.
