DHCP addresses often shuffle on reboots. I don't trust ISPs to keep completely accurate records or give them out in a correct manner if they do.

How hard could it be to keep DHCP logs? Assuming they exist at all, what would cause it to be incorrect?

I'm sure they exist. I think the point is more that you shouldn't need to trust your ISP's record-keeping to avoid life-alteringly big fines.
