I agree something needs doing and fast, but the charge is strange . However, it puts a few more wardens on the street to check for frauds, then I would happily pay double that again.
A lot of the problem is with Private Car Parks. Ie. Supermarkets. Their blue badge areas are not covered under law , and the fraudsters know that. Also the supermarkets refuse to engage anyone parking without a blue badge. Other private Carparks will fine for non compliance, and this is the way ahead for the supermarkets. Its no use saying you are providing 20 disabled parking bays and then not doing anything about it when Lazy Joe decides to use it for his convenience.
