It's quite possible for a forum to see the proxy IP as the real IP for the end user, it depends how clever it is in reading the HTTP headers passed out - if you don't realise that the IP you're sending the data to (proxy) can be different from the requesting IP (real end user) you can easily think the proxy is the end user.

This has happened in the past, the easiest way to check is to do a DNS lookup on the IP and see whether it is a customer IP (which end in broadband.ntl.com or cable.ntl.com for broadband customers and contain the word 'cust' to indicate a customer) or a server (which end in server.ntli.net).

Dial up and broadband IPs are assigned by different systems and thus have different pools.
