I've been spending some time considering the future technology stack of Beehaw. I'd love to work on some kind of moderation tools, especially because I know that they could be inserted alongside the existing codebase - even if in an exceedingly hacky way. Heck, even client side site scraping with content matching is an option if for some horrible reason we had to.
The fun part is not being able to ask those who run the server about specifics for what's needed.
