Since my cousin Ben has announced that I am his new Co-Administrator of the Cooper Surname DNA Group, I will add my "two-cents worth" to this discussion. By the way, prior to mine and Ben's genetic matching through DNA, I couldn't call him cousin with any confidence. I just knew him to be a kind and considerate fellow researcher in cyber-space that was always willing to help me in my research. Many people are still wary and suspicious of giving a DNA specimen for testing, and even of those that will submit a specimen, many are very cautious about giving out personal information. It is all kind of tied-in with identity theft scares, and the suspicion that someone will do wild and crazy things with their DNA. Some people are afraid of "Big Brother" watching and taking an interest. Because of all the above, the DNA testing service providers such as Family Tree DNA, and others, are extremely protective of each individual's privacy. They will only share their email addresses with other participants whom they match, and not even that if a participant does not want it shared. The Family Group information that Ben has placed on the website, has been done so with the submitters agreement. Others for reasons of their own have chosen not to publicize that information. The results marker numbers can only be shown associated with a kit number, to insure privacy of the participants. It is much like the "Y-Search" option on the Family Tree DNA Website, or another website known as YBase. The value in the numbers to participants is seeing how many markers different from their own, other participants are. I agree that it is counter-productive to other researchers to go to the expense of taking the tests, and then not sharing family data with others. It seems to defeat the purpose.
