Today I received a phone call from one of those automated political telephone campaign recordings. The number was blocked though! That really suprised me. As far as I know businesses of any sort must be listed and can not block their number. I realize that political campaigns, legally speaking at least, are not the same as businesses but I was thinking that the same rules would still apply. Am I wrong? Does any one know if this has changed or if there is an excption somewhere for these sorts of calls?
