It may select all your friends (lets say 5,000) and say invites sent, but will actually only send around 40 - 50 of those invites.
how can you know that? i hear this and i hear other people saying its a lie, remember there's always some liers because of the competition or to sell sofwares, i never seen a proof of what people are saying.
Its been technically tested. It was introduced by facebook to stop pages going viral in like 5 minutes..
50 at a time? or i have to wait a specific time between the 50 invites?
