While this behavior is usually frowned upon by forum administrators, it tends to be somewhat less than convincing. However, Tycho followed up yesterday with more information from somebody who seems to have a lot more in-depth knowledge of how some of these guerrilla marketers actually work. The methods he describes are far more complex than the simple "extremegamer953" technique.

Their technique is quite insidious. Let's say they were hired to pump up PA (not like you need the buzz, but whatever...). Using one of the hundreds of shill accounts they have across the net, they post a new thread that says something like "hey guys, I've been looking for some new web comics to read. Anybody have any recommendations?" This is non-threatening, and gets the community engaged. They then wait a couple days and post again, this time with "Well, I asked some friends and they suggested I check out Penny Arcade . I thought it was pretty funny, although I didn't like all the cuss words. What do you guys think?" Again, seeking engagement, they now have stealthily inserted the client's link, thereby encouraging trial. It's all very measurable and very effective. You should see the monthly reports you get from these guys: everything is detailed.

Given the level of long-term planning and maintenance in use there, one wonders whether the more straightforward shills are deliberately planted simply to alleviate suspicion from the more effective ones, by adjusting readers' expectations of how such marketing works. The case quoted above describes forum behavior that in general is perfectly benign. It would be interesting to know how many of these firms exist, and how frequently their services are employed. It seems that they are by no means limited to gaming.
