My mistake, apologies. I saw this sub recommended to someone else in a thread over at Lemmy.world community discussing something tangentially related but I realise now I may have missed something important as to why it was recommended to them. I previously posted this question in a lemmy.world thread but people did not understand my question lol.

It’s a pretty bad oversight, and makes me think the best thing to do is temporary mutual defederation until it’s addressed which obviously isn’t ideal at all, but I do worry about the implications of so many reasonably sized communities being completely unmoderated on our end. Thank you for the advice tho, I’ll make sure to save your comment so I can refer back to it if this isn’t fixed!

It can be quite difficult to find communities especially using the app unless you see a post in all and can just click through.

If you open up your browser, open feddit.uk, click the search icon and type !https://lemmy.world/c/gunners I think that should work. You have to search from your ‘home server’ (the site you signed up on) so you remain logged in. It’ll give you a link, and when you open it you can hit subscribe that way. Much easier to just click the sub name from a post in ‘all’ tho.
