The `min post length` site setting should work here.

See [Discourse Akismet](https://meta.discourse.org/t/discourse-akismet-anti-spam/109337), and also search for `spam` in your site settings to see other useful settings, like the `newuser spam host threshold` and the `allowed spam host domains` may be helpful here.
