Since lemmy.fmhy.ml and lemmy.fmhy.net is no longer online. I would like to suggest lemmy.world and other instances to delete any communities and posts from these two instances that are cached.
The reason is that new lemmy users may join these communities as they find them in using the search on lemmy not knowing that they do not exist anymore since their domain name or hosting is forever gone.
Not sure what happened this time but last time it was due to loosing their domain. FMHY was the first instance I joined and is now the reason I self host.
