facebook percentages

what percentage of all the 500 million facebook users are real humans, but more specifically marketable?

Once you exclude all the disabled, roadblocked, duplicate, ewh0re, spammer accounts how many are left? And then when you exclude those who are from Turkey, south America or farmville/mafia wars you have even less.

That leaves maybe only 200 million accounts that are potentiality useful to marketers. a reality check for those thinking facebook will be the next Microsoft or google lol

500 million are only of active users

yea but spammers are among the most active. think how many accounts russian spammers have. then there's the phished accounts, too.
