Before I start getting a bunch of fucktards in here screaming SPAM! yes, this is spam, but from what I can see it seems as though it could be pretty useful spam. That's up for you to decide, take a look at the site and see iftheir offer sounds like it will work for your needs.
I came across this new SEO company that is offering a 120 day free trial, claiming to get you top position in google and 39 other search engines for 5 selected keywords, within the first 3 months after you signup. After the 3 months is up the basically hold your SERP ransom, and if you're happy with where it's at you start paying them for their SEO services at this point. I've dropped a couple mainstream projects into it myself and am waiting to see what goes down. Not sure what the status is on adult stuff, but I'm looking into it.
