My question involves criminal law for the state of: California

What is stalking? Can a pickup artist get arrested for asking a woman he doesn't know out on a date? What if he accidentally asks her twice or more because he didn't recongnize her? I mean what if he asked her out years ago and didn't remember ever doing so and asks her out more than once. Is stalking asking a girl out on a date twice or more times?

How does stalking relate to online dating? is asking a girl out twice or more when she said no the first time stalking? You see in online dating it is very hard to keep track of who you've contacted if you message a lot of girls.

You see I read that a pickup artist was once arrested for approaching a girl in a store more than once on accident and the approaches years apart and was charged with stalking so I want to make sure that I never do the same or get arrested for the same.

You see pickup artists don't mean any harm but they ask out a lot of girls and cannot remember every single one leading to possible asking out a girl twice because they don't recognize her.
