This was an odd one, as far as my experience of spam bots goes - as it did actually lead to a page with links to Buddhist articles and stuff (rather than a hair loss or "blue pill" page which tries to download x amount of trojans on to your machine!). Suppose the Adwords was there to give a clue that there is some monetary benefit to getting traffic to his page...bairy said:They're spambots. They put the site they want to spam in their signature then pm people with something that doesn't make a lot of sense. In theory they want you to click the link to figure out what they're talking about.
Luckily they aren't made very well since they usually message someone who can ban them, James2's case it was me.
