@flamingos@feddit.uk when I post on a Lemmy community I always follow it first, so I should receive everything that is boosted in theory. For comparison, I do the same with Guppe groups and it works as you described (as long as the group is tagged)
I don't have a Sharkey account to test (I really need to move my masto off .social one of these days) but it works in Mastodon
