Add friends without getting blocked

So i need to add as much friends as I can to my profile , but Facebook hardly lets me send more than 5-10 requests per day , crossing which would result in "Friend request Blocked for 2/7/14/30 Days" . Also , if people do not accpet your friend request , Facebook may block you then as well.

Is there any method to send more friend request and be safe from getting blocked even if my requests don't get accepted ?

Any other tricks to increase friends ?

You can make another facebook accounts and also suggests friends from that account to your real accounts. This is the one way to get more friends on the facebook.

Join games groups like "hidden chronicles" or "castleville" and post that you need neighbors. You can get several friend requests from there.
