I agree. I think safeguards need to be put in place. I think it's OK for a computer algorithm to use historical information to provide relevant ads and filter out all the rest. Ideally, no one else would have any access to that data. It's more work, but I think it's worth the effort (there's way too much junk advertising out there).
