Website that allows user subdomains - what subdomains should I block people from using?
My website is going to allow users to choose their own subdomain. I've got quite a list going but want to see if there are any others out there that you think would be worth it...

Thanks in advance!

    $banned_subdomains = array(
		'cname',
		'www',
		'test',
		'js',
		'css',
		'cache',
		'static',
		'img',
		'images',
		'mail',
		'ftp',
		'cpanel',
		'whm',
		'webmail',
		'webdisk',
		'ns',
		'ns1',
		'ns2',
		'ns3',
		'ns4',
		'ns5',
		'register',
		'pop',
		'pop3',
		'beta',
		'stage',
		'dev',
		'http',
		'https',
		'abuse',
		'admin',
		'donate',
		'store',
		'payment',
		'smtp'
		);
