To #Guppe creator,
Something needs to be done with the following:
1. cross-posting
2. off-topic content
3. boosting replies
For #1 and #2, I have no idea what can be done with those other than a constant reminder. Maybe add a feature for assigning moderators for these "accounts"?
Cross-posting is fine if it's on-topic, but there are people cross-posting with 3 to 10 groups, and not a single group is related to the content.
For #3, I think boosting replies should be disabled, especially since are cases when a boosted reply is disconnected from the original post, the context is lost in the fediverse.
The original content should be more than enough, at least the context is easier to track down.
