Ancestry review: Privacy

Within the last 2 - 3 months I have noticed I am getting contacted by quite a few people through Ancestry who's only intention is to either scam or be "looking for someone to date, etc." I'm 72, been married for 50 years and need neither. I love geneology and have found out quite a bit about our family history because of other family members research (the old fashioned way) or just by paying attention to my elders while growing up! Every time I log on I get "Hello dear, how are you today" "Hope you are doing well!" , etc. I usually block them and in some cases they magically are unblocked within a few days! There seems to be no way to delete them. Today I finally answered, "Are we related? I got back, no I just saw your name and thought it would be nice to meet you! He came back he has a son, he is stationed with the U.S. military in Syria and now I am REALLY concerned! I told him my account was for my personal research only. I am afraid if this "harassment" continues I have no recourse but to cancel my membership! I have not mentioned this to my husband who will probably be mortified! I doubt there will be any changes but I'm sure you will hear from other Ancestry members.
