Why are people so dumb as to believe some random website on the internet as gospel?

This woman on a dating site looked my number up, and said
"I was looking forward to our chat today, but when I saved your number to my phone, I did a quick search (got to be safe!!), and it says that you’re married.

I wish you well, but I’m not comfortable continuing. Take care and all the best."

IMMEDIATELY blocked me. Guess I dodged a bullet if she is going to just make an assumption off some sketchy internet site. Not married, NEVER have been married. I think sometimes these moronic sites confuse me and my father (who we don't even talk to anymore), his name is similar.. and he's not even married to my mother now, so it's wrong in multiple ways.
