There Are Limits on Who I'll be Imaginary Friends With

I got an email from Facebook saying, "ناصر علي added you as a friend on Facebook. We need to confirm that you know ناصر in order for you to be friends on Facebook."

I have absolutely no idea who ناصر is, so I'm thinking that "ignore" may be the way to go. Even I won't automatically decide to be imaginary friends with random guys from Saudi Arabia.
