Actually, when a person has touched lives of so many people in a very good and profound way, he cannot escape a bit of attention back. The enquiry "are you ok?" is human and not evil.
Stalking _why online doesn't turn into Internet stalking. If I hunt a guy down in real life, but all I do with his family is talk to them and see if he was okay, I'm not stalking them. I'm just contacting them.
