Blocking Premium Rate Numbers

There have been a lot of people who suffered lately because of premium rate number fraud.

Technically, there is no reason that premium numbers can be blocked selectively.

Especially as the sensible ones, such as computer support are in different groups to those which you generally would not want to ring. Even legitimate very high rate numbers which top up special Internet services such as micro payments and text messaging are in a different group to sex lines.

It would actually be a selling point for a telephone service to allow this selective blocking to be performed. But for it to be economic and comprehensive, it would probably need to be performed using an automated system over the Internet or through a touch tone phone menu.

But many would pay a small fee each year for peace of mind.
