Men... Spinoff... Jodi Arias/Women Stalkers

Men, in light of the Jodi Arias case, are you going to take stalkers more seriously?

If yes, what steps will you take to avoid getting hurt/hemmed up?
If no, why not?

Also, what are your warning signs/red flags that alert you that you've got a Stage Five Clinger, or worse, a psycho?

Thanks in advance.
