I don't know how or why this happened but my HWID is not unique to me.
On the stats page for C4S (which uses HWID to identify players), I have apparently played under 15 different names and used 18 different IP's.
I'm trying to become an admin on C4S but with my HWID not being unique, it is possible that these 15 other players will get the same privileges, so it was suggested I make a thread here about it.
The correct combinations are those which locate my IP in Ireland and have the name " [IRA] Chopper". I expect my IP to be different sometimes, given that IP's are dynamic but I have only connected from Ireland. It says the first connection to the server with my ID ending in " a2e26a21" was in Poland, I never use a VPN or proxy for COD4. It also shows connections from America, Turkey, the UK and India.
I can say I have a common combination of hardware  but even then, each component should have its own unique ID. PC isn't a pre-built, all parts are new other than the GPU. BIOS is on latest version, only changes made to it are for overclocking and VMs.
 Ryzen 5 2600X, PowerColor Red Devil RX 580 8GB, 16GB Corsair Vengeance 3000MHz with COD4 installed on an XPG 256GB M.2 SSD.
If you need any more information, just ask. Thanks
