You should report them as spam, because they are. There are now regulations against this in the US.

I like how one of those was called the CAN-SPAM act. Others have been similar.
Slowly, as more people opt into it, we can make it opt out, and then get rid of the old protocol completely. If some countries don't want to adopt the new protocol, well tough luck at that point but I think it is fundamental for us to be able to trust caller ID before we can do anything else.
