Receive many phone calls from 1-417-800-2511 asking for Japanese male 18 or above to participate in a studies. My number is unlisted and registered with the 'do-not-call' list. The rep on the phone was unable to clarify how they get my number.
There is a lot of babble on this subject. The best thing to do is a fast hang up. I have had luck with this and get less calls - but they go ring in now and then. Lets face facts until the people in the government make it mandatory to have accurate caller ID's listed were stuck with the spam calls.
As to Ken and the other long winded writers they have nothing more to do.
