Also, most ISPs nowadays uses some kind of NAT for some of their customer addresses
No, what most ISPs use is something called a WAN pool. It's kinda like DHCP for their users, and not at all like NAT.

Anyway, most ISP use 7 days lease, so if you do an IP Block you leave it for 7 days... since you know that by that time the idiot you blocked will have changed his IP.
Which only reinforces my point. So, what were you adding?

Still there's way to know if a given IP is from the DHCP pool of an ISP or if it's a real static IP.
Other than looking at the reverse? I'd like to hear about it. If the reverse reads like "3400075-city-state-airportcode-xxxyyy" instead of "Mookie-and-[]-have-a-love-nest-they-would-like-to-share", then you can probably determine which reverse is a static IP as opposed to a WAN pool IP. But if the person with the static IP isn't [] or Mookie, and decides to name their reverse in a manner that looks a lot like the reverse of a WAN pool address, it'd be hard to tell them apart.
