Indeed. This subject came up on a BBC program only yesterday. It seems that once you have ticked the boxes on any website that says 3rd parties (even by mistake), you really are opening a can of worms. Do you know who these 3rd parties are?
Strange to say though, I never get these calls to my mobile or on the land line. Simply because I never give out the land line number to companies. Currently I run an app on the mobile that prescreens calls and if it isn't in my list, it don't get through. No number calls are ignored / blocked by default. Ruthless? Certainly.
Same like I have multiple email addresses. Companies get my hotmail account with it's default as exclusive. Not on my mailing list.... junked.
But it really would be nice to be able to block calls easily.
