Both of those posts previous to yours are by strategic spammers as far as I'm concerned. People paid to take a little extra time and infiltrate boards with links to their contracting vendors. I could be wrong... but I don't think so. If one looks at all the previous posts by both, they are all sketchy. Links to a site and a "I recommend" or an "I used this" etc. And the language used in them, could be some person in India. I'm clicking the spam link on both of them in the upper right hand corner and going to let the mods sort them out.
Strategically, it looks to me like it works like this. Multiple vendors pay into an internet message board promotion plan. So, these guys doing the message board promotions then have several sites they start pimping on the net. Sort of a broad coverage, long term, internet promotion for companies that pay into it. Then these guys that get on the net and promote, take a little bit more time to read the thread and try to make their posts seem relevant so they don't get found out right away. Longer term internet promotional saturation. A little different than the obvious spammer that gets a link up for an hour or two, they try to take the time to insure that the links stay up forever.
But I could be wrong.
Edit: The mod gods removed the traitorous posts and the entities that preyed upon our unassuming good natures, and our pocket books. Praise the Lord.
