Yeah, experience from moderating over at !coys@lemmy.world is that you've just got to keep posting and posting and posting and gradually, very slowly, the numbers creep up. Same on Mastodon on the #MastodonFC and #COYS tags (can't speak for other clubs). You've got to give people a reason to come back.

Personally, I'm not sure the individual posts containing a single goal from a specific match is helping much. Makes the community seem very noisy. IMO would be better to have one thread per match with goals posted as comments. But I'm not mod here and others may feel differently, so ¯_(ツ)_/¯

FWIW, I don't see the community as dead. I post a few things here and there's often a good number of votes and some good discussion. Seems far from dead to me.
