Seems like an interesting effort. A developer is building an alternative Java-based backend to Lemmy’s Rust-based one, with the goal of building in a handful of different features. The dev is looking at using this compatibility to migrate their instance over to the new platform, while allowing the community to use their apps of choice.
The ones on the Sublinks roadmap are interesting, for instance the warning system: https://github.com/orgs/sublinks/projects/1/views/7
Create a way to create a warning system for users. For example, a user gets a warning for posting a broken link multiple times. We don’t want to ban them for that. Or a admin gives a user a Warning with a reason. Create a rules system for auto actions like banning for some time or forever. Consider adding types of warnings. This should also track bans from communities for admin-level auto actions. The profile page shows strikes similar to Mastodon for Mods/Admins only and the user that owns the profile. Examples, warnings in each community, and bans. Rules will be applied to counts of warning types or total warnings over time. 3 warnings within a month is a ban for a month, for example.
There was also this list from a few months ago: https://discuss.online/post/12787?scrollToComments=true
True a warning system makes sense.
