It is the same with all IP-lists, at least what I see of it, many of the IP in the list will never attempt to contact you, on the other hand, the listbuilders might miss IP pounding your ports like crazy. It is just a gamble who is in your range to bug you. So to be on the "safe" side you can start with a list that pretends to hold most IP that may or may not do you harm.
Ideally you would have an IP-blocker that could analyse the traffic on packet contents and block whenever it is suspicious, just like the community patch blocks fake files.
This said, no list then when it contains 0.0.0.0-255.255.255.255 covers all. And as you will understand, such a list is unusable though it will be very safe.
