Some people are engaging with the weekly posts on !incremental_games@incremental.social (sadly having federation issues) that are in theory using a bot, but in practice mods have been manually making the post. But people engaged when it was actually the bot posting too.

!fedigrow@lemm.ee, !newcommunities@lemmy.world definitely have weekly posts that get interacted with. !letstalkaboutgames@feddit.uk used to, they are not regularly posted anymore, but when they are people interact. However, on all those communities, as far as I know (I think the post scheduler posts with your account so for all I know the bot could post it?), humans are making the bog-standard “what is going on in your community/active communities/what are you playing this week?” posts and I wonder if the fact a human is posting is what is driving the engagement there.
