Why would someone send a facebook friend request to someone they don't know?

they think you're hot

or

they want more friends to make them look more popular

also could be because they're lonely & want to meet & chat to new ppl or a very small chance it's because they have u mistaken from some1 else.

I get friend requests constantly from total strangers simply because ppl think I'm hot! Well that's what they tell me!

Yeah I get requests like that all the time, but I usually ignore them because I don't like to add people I don't know, I don't want them to look at my profile. Maybe there psycho freaks or something. I only add people I know.

To give them the benefit of the doubt, they might have confused you with someone they know/used to know, who has the same name as you.

or

they are desperate to increase their friend count

or

they are scam artists hoping to get your personal details.

I had a couple of people I never met request friendship with me because we do the same style of karate and joined the same Facebook group. I didn't accept but one of my karate friends did and she ended up meeting one of them. She is now she is building a very expansive international network and karate contacts!

Well, the person that adds you might want to get to know you, or they heard about you?

umm

if you dont want to be their frend then juz ignore the request...simple as that~

dont make a big deal out of it

maybe they think that they know you from somewhere before

may be they want to be ur friend."net friendships"
