The proxy hides/changes your IP and the mods of VTCOA would never be able to see past the proxy. The proxy does not hide your internal ip to your own network, ( LAN) it hides or changes the ip of your ( WAN ) browsing ip or external IP.... It would make no sense to hide your internal ip because its not broadcast to the world in any meaningful way ..
That is the reason people will go out to walmart pay cash for a pre paid visa , and then go to starbucks use there internet download and install a proxy server then go back to their home and download illegal content or do illegal activities.. that way when the police go to the proxy company and ask for proof of who purchased that product their is no link to that person and they can practice their illegal ways with little worry of being busted ( with out a full on FBI ) investigation.....
So a proxy server will hide you from who ever is looking and for a vtcoa prank a site like hide my ass works perfect..
.. just sayin
