I think most people on BHW know that FB measures your acceptance rates for friend requests. I believe that it's the case that if your acceptance rate isn't at or above a certain level, say 60%, then you'll get warnings when you try to add more than 2 or 3 friends. What I'd like to know is do they measure acceptance rate as measured over the lifetime of an account or do they check your acceptance rate for, say, the last week or some other period that isn't the full lifetime of the account. As an example with some nice simple numbers in case the above isn't clear: If I make 100 friend requests over the course of a week and they are 100% accepted then my lifetime acceptance rate would be 100% and for that week or period my acceptance rate would be 100% too. If a month later I make another 100 requests over the course of a week and zero are accepted then my lifetime acceptance rate goes to 50% whereas for that period my acceptance rate is 0%. Anyone know whether it is lifetime acceptance rate or acceptance rate in a specific period that matters?
