There's no "friend" system of FF.net. You can add people to your "Favorite Author" list, though.

Also, I've never experienced spam from FF.net. To tell the truth, I've never heard of anyone being spammed. They send you email alerts when different things concerning your account happen, though. You can set different email alert settings in your profile page.
