I agree with you that is likely a blatant attempt to copy NSQ but we don’t exist to moderate which communities get to have visibility or not unless they violate the rules of this instance or this community. They do neither and as such they get to advertise here.
It’s Google and Microsoft tactics.
!actuallesbians exists as does !talesfromretail. Though they might need to be searched for on your instance before they’re federated.
If you could edit in an instance-agnostic link (!communityname@host-instance.com) for example: !newcommunities@lemmy.world would be this one.
Makes finding your community on other instances easier (and is technically required for our formatting rules)
