First of all, sorry, I had "can" in my post above where I meant "can't".

The code you posted is in profile.php, at that point the user is already registered. So you could exit at that point but it will only stop the user from setting the profile. But if you want to do that, you could put:

if (!empty($vbulletin->GPC['homepage']))
{
    exit();
}

But that would also stop any user from setting a homepage.
