Granted it is a link to my [small and non-advertising driven] blog, I make zero money on it, but I did link to it and I was able to get my hands on four beta keys to a pretty radical game, so I posted about / promoted it in an RPG forum. Is that really spam? Maybe technically, but at least my blog received loads of interest in the keys which was my main goal. No one is making money here. I'm a one man show promoting my content where [I believe] people are interested in it. If it put anyone off, it shouldn't have.
EDIT: All of that being said, it's still a sick game, I've been playing it for the past week, and if anyone else is interested, please discuss it! As an old school DnD fan I was waiting for something like Heroes of Neverwinter for ages.
