This was quite funny. Got a spam mail yesterday that normally would have been junked with a speed but it got my curiosity and visited the link.
Quite correctly whilst the consumers need protection, there is a limit and the new consumer act could give them the right to "not pay" or abuse the system to not pay.
Cheapskates.com (didnt put the link on purpose) has been launched by this guy that has obviously had a run in with consumers!
You get the opportunity to black list your consumer here... to funny. Not sure about the legalities, really have my reservations about that and dont know if it will really take on big but certainly makes a good point.
Wish him luck anyway
