People who use the internet are about to get a new opportunity to complain about company websites. From 1 March, consumers are being invited to make official objections about indecent or misleading information on the internet. They will be able to complain to the Advertising Standards Authority (ASA), which is taking on new powers to regulate commercial websites. Up to now the ASA has only been able to monitor traditional advertising. These were generally on billboards, in newspapers or on television.

I wonder if you could complain about fake items or collections of e-books, being sold through auction sites?
