it should eliminate the numerous bots that won't pay $8 ea for the privilege. Just like my (old) concept of charging even modest postage on email, that quickly makes it uneconomical for spammers.Except for the fact that paying won't actually eliminate things like ads. So you are still the product, just now paying for the privilege. What a deal!!
