Who the hell are you people?

I have noticed, as of late, a number of names on my "Also friend of" list that I honestly am clueless about.

Just people who have randomly friended me, but have never actually spoken to me or anything. That's always confusing.

These people are:
911agency
dagfari
equusentric
estrelladesax
gible
iabrocci
izzat
kinzokutaka
mlina
nemjersatyr
ragnarokt
tiajuanabible
triplemare
ziggyxxstardust

If your name is on that list, and you're actually reading this, I have a few questions for you, if you don't mind.

1: Who are you?

2: Why did you friend me?

That's all. I'm just a curious person, and I've been wondering this for some time.

(If your name is not on the list, don't bother replying to this :p )
