you can add as much as you can in a day, but better try not to send false request. The site is for you and its your duty to keep it working smoothly. especially boys don't send friend request to girls at a random basis.
few weeks ago i read in an ebook that we can invite about 400 people a day at max by email on fb is it true?
I read there is a total limit of 5000. After 5000 Friends you will get prompt even you will be banned that you can not add any other as well you can not like to else.
Only add as many friends as you think you would if you were using FB legitly. Or you could just use it legitly.
This depends on how you go about it, if you go on adding people you are not familiar with, you will be given infraction and possibly have your account terminated. But you add people who you know and related to your friends on your list, you wouldn't have any issues.
There is no limit for adding friends in facebook per day. You must only send friend request to the peoples you know. Since facebook is network based social networking site, it easily recognize whom you know.
There are few ways to add much friend in facebook account without any risk. The best way is add 15-20 people at once and then gve a break for 3 to 4 hours and again add 15-20 friend. I added lots of friend in my several account in this way. There is another way to add friend like from your browser you can open as m.facebook.com and then add lots of people as a friend at time. But sometimes its very risky. My few accounts were banned.
