For support tickets, we currently have an "approved" column that saves whether the ticket has been marked as ham (true) or spam (false). We don't do this for abuse reports, and there's no real reason to do it here. We can just run the report through the spam checker and send or reject it based on the results without saving said results to the database.
To test, make sure you can still send a Support ticket. Also try sending one with the email field set to firstname.lastname@example.org, and make sure that ticket still gets rejected as spam.
