I made an article for free domains and subdomains. With these subdomains you can cloak youdomain.com with subdomain.com.com. Even though subdomains have less seo on the net. The traffic they generate from cloaking and redirecting can be substancial. Example youdomain.com is cloaked or redirected by subdomain.com.com. Every time somebody types http//subdomain.com.com then it will go to youdomain.com. You can also make a site for your subdomain.com.com. Here is the full article and list of free subdomains. http://urslink.com/subdomain
I did not read the article (because I have no interest in cloaking) but if you are using that term properly, your readers should take careful note of the following: http://searchengineland.com/googles-definitive-cloaking-video-99651 This is Matt Cutts (Google) about cloaking and the risk it poses for your websites. Use cloaking at your own peril.
You should read the article its about the list of free subdomains like subdomain.com.go for you own use its not just about cloaking. I just mentioned cloaking once in the first forum post that word isnt even present in the article that I made. I watched the video was informative about cloaking. Just Make sure that the content that your users see is the same as what googlebot see's. Make sure your cloaked subdomainname is relevant to youdomain.com if i got that right. Free cloaking services have been online ever since i even knew how to use the pc. If you are using free subdomains it doesnt have to be indexed by googlebot to be usable, i think i there is no violation there. You can also use redirecting. Make your own blog or website using your newly created subdomain. you can even cname them to blogger. just dont do high risk stuff like a violation of google terms. please read the article.
