Facebook Friend Request block

Hi! I tryed to build some accounts on facebook with maximum friends limit. I couldn't do this because facebook keep block my account because i'm sending requests to strangers...how they realize if i know or not a person, and how can i pass this problem ? Can anyone help ? Thanks.

Same problem to me, I think the new features blocks you sending requests. I uploaded a list of 100 email list because there is no limit to invite friends via email b ut facebook blocked me forwarding the invite stating you should send invites only to frinds and you could be banned if there are several reports against you.

DO anyone have latest friend adder system?
