Another player down the thread characterizes this as Blizzard caving to demands made by Activision. Tigole appears a few comments down to ban the first commenter for "trolling," adding that the game is still being worked on. The second of the two commenters mentioned is then handed a ban by Tigole as well. One of the response threads that appears to have survived is here, with a set of reactions ranging from sympathy to Tigole to a recountment of EverQuest history to concern over how the two players were banned.
I'm somewhat torn, and had wondered whether the whole thing was a joke; I've not seen Tigole appear on the forums to ban people before (although it's entirely possible he has and I've just missed it). I've seen worse behavior on the forums escape official comment, but it does seem as if the number of complaints (rational or not) has hit fever pitch on the discussion boards. And -- let's be frank -- a lot of it does seem like pretty pointless carping. I've had a chance to see the beta myself now, and I don't think anyone could realistically accuse Blizzard of skipping its usual attention to detail (indeed, the only running complaint I've seen on the beta servers is that they're too popular). Still, these particular bans seem a little out of the ordinary, unless there's something going on I haven't seen.
