Solus has been leveraging the Akismet support in Flarum on our Flarum to block repeated Chinese-language SEO spam. While this support has been fantastic and has reduced our workload substantially when it comes to clearing out discussions, it doesn't handle one part of the moderation that we believe would be valuable.
All of this SEO spam comes in the form of one post in one new discussion / topic. It's never being posted in an existing topic. So while the plugin rightfully flags the post itself and marks it as not approved, if it's the only post in the discussion, it doesn't remove the discussion itself (which can always be restored by an admin should the akismet flag something that is a false positive). This means you'll have loads of topics, all which have a spammy title, with no actual content inside it, and this is all viewable to the user.
I'd love to see the Akismet plugin automatically remove a discussion if the flagged post is the only one in the discussion.
P.S. I would've filed this on the Akismet GitHub but the issue tracker isn't enabled for it. Not sure if that's intentional (to encouraging filing against core) or not. 🤷♂️
