search engine promotion

I just found this tonight - searchenginecloaker.com

is this for real? has anyone used it? or is it just a gimmick?

The guy that runs that site is one of the best known search engine spammers on the internet. Using his own techniques, he has by his own admission gotten some of his own sites banned from search engines. I would take what he has to say with a very large pinch of salt.
