guide users posting content that could fit better in the communities we're now support is that, when being told not to post there many seem to get overly defensive, not realizing we're asking them to do so for the health of the platform in mind.

This has been an eye sore when browsing some potential communities to join in. Strangers joining a community without interacting and posting topics irrelevant to what the community wants to see.

Maybe some layer of verification done by the community mod/leader prior to seeing the post visible on the community page of peakd. It doesn't prevent the person from posting on the community page. It just adds a layer of protection from spammy posts being visible on the community page.
