Phone filter flaw in UK

Which?, the UK's "Consumer Reports," found a loophole in mobile-phone parental controls offered in that country. The filtering system does block adult content sent directly to phones, but kids can buy access codes over the phone (for 1.5 pounds or about $2.60 per code) to get into "Web sites showing hardcore sex films" on their computers, the BBC reports. "The consumer group said the number of pay-per-view Internet sites accepting payment by premium-rate text messages had increased over the past few years." O2, the phone company whose service Which? used for its test, and the trade group for cellphone billing services said they were working on closing the loophole.
