or maybe the old skool option of paid upgrades? $10 first time fee to get the current list. then, as you start to notice things not getting blocked, purchase the upgrade/updated list?

I guess it depends on the monthly fee? $10/month, nope. $12/year-$1/monthly or $10/year-1payment to get monthly updates, quite possibly. i do understand updating/maintaining a fresh list will cost someone somewhere money.
