Like I said, there was a part of valid complains.
But too many posts contained obvious lies. Those are or shills, or especially naive and dumb people.
Also, there are people who are not "shills", but made a choice quite long ago, and who still spent lot of time on Nostalrius' forum, bitching about every single thing. Those are maybe not to be called "shills", but "jerks" fits quite well. If another server was out before Nostalrius, and I wasn't happy with that server, I wouldn't have covered their forum with complains or even with advertisements for Nostalrius. There is a big difference between giving a negative feed-back or starting a propaganda campaign
Anyway, there is a huge difference on forums, while there is almost no difference in game (in term of population). Sincere reasons or not, it is obvious that a small minority was making far too much noise for the importance they had.
