Just block their IP address until they pay up.

Putting unfettered, free versions of commercial software on the Web for all to use is a bit thick, though. If I were one of the technical staff of entitledto.co.uk, I would only allow use of the tool after people have signed up and given their e-mail address (verified in the normal way, of course). That way, it's easy to pinpoint offenders who should be paying in cases such as these. It would also be reasonable to give a trial, where the software could be used once per fortnight unless registered and paid for.

But in summary, this is just another example of stupid decision-making from yet another British company, who expects everyone to pay for its mistakes. Not impressive. As the councils, everyone should know they are penny-pinching buggers - and they'll do anything (including oursourcing call centres to India) to save a bob or two. Knowing there are organisations like this out there, it's practically a given that free software on the Web will be used for commercial purposes. This should not be any great surprise to anyone.
