What are your thoughts on ticket-and-request schedules and DNS records.
These sites use money like anybody else.
I wrote this programming code that simply puts a request for DNS records, however it makes sure the request is valid and not-insecure.
This will return a list of DNS SPF records for a site. Which are insecure according to the UK OPs office.

(again this is a work in process)
It is not the idea, it is the choice.
