I remember a similar scam re parking charges occuring at Luton some time ago. After many complaints they put up a notice on the Light Aircraft stand warning that parking charges would be levied after two hours and, also provided access to an alternative parking area where a flat fee,(reasonable), was charged. Although I'd be the last person to say Luton was GA friendly I think this could be the way to go for Blackpool because it's quite obvious they're not going to get repeat visitors if they go on like this. I've always found Blackpool Airport a GA friendly airport to fly into but it doesn't take long to get a bad reputation if they carry on with concealed charges like this. Anyone from Blackpool Airport management out there? Listen to your customers.
