zeogold: Actually, that much I can understand, but I'm still trying to figure out what brought him into prominence enough that GOG got worried about him looking too official.
Consider the number of threads on Steam, how much total time employees on GOG look at Steam threads, how many of those threads that Pooka is likely to comment in, and whether the employees read far enough in the comments to actually see Pooka's comment, and it isn't as surprising. And that doesn't even get into whether the GOG employee happened to notice that Pooka isn't actually affiliated.
Could just be that someone from GOG finally happened to read a Steam thread long enough to see Pooka's comment, read the username of the poster, and realized that Pooka isn't some unknown co-worker.
