I did a report on a game update, since there's a newer Public version out on itch.io than in the OP.
That said, the rule about marking "abandoned" doesn't apply to "news". It applies to Updates; actual content. If a creator keeps giving news on a game, but no new updates/content, then it stays abandoned. See
Hero's Harem Guild for example as that one had a lot of drama around it being marked abandoned (though less so currently since there still hasn't been a new update released).
Is there any difference between subscibestar updates versus public updates? or is it just that the subscribestar ones get released earlier before public?
