Firstly, congrats on releasing a plugin. From experience, I know it’s a non-trivial acheivment!
I’m interested in this type of plugin - in my case I’d like to avoid people dominating certain “firestarter” topics. Although I’d like to deploy a softer implementation that perhaps rate-limited users as opposed to preventing users posting
In fact, it seems a bit heavy-handed to allow the user to take the time to write a post, only for it to be immediately closed/unlisted/deleted afterwards.
With this plugin, I think it would be friendlier if the composer UX was modified to prevent a user wasting time posting a new topic if they’ve reached their limit.
