Even with dynamic IPs (Not NAT in this case) it's not a problem as ISPs in most countries have to keep a record who used the IP at which point in time.

To disambiguate customers the ISP would need to log every connection, which is a huge amount of data to keep track of and only useful if you have not only the IP addresses and timestamps but also the peers' port numbers.
