As of now, they are only generic. But I'm aiming to have categories soon, so you can sign up to receive clown warnings but not shark attacks. Users will then be able to classify warnings by category when they report them as well.

(though how would one categorize clowns attacking sharks??)

Probably the 'Absurd' subcategory of 'Interspecies Violence'.

Thank you for the clarification, best of luck with your project.
