What is the prevailing theory about the origin of the trolls in this thread? They seem to arrive mid-late bear markets, are completely belligerent, and speak in broken English. They are overly hostile and their methods are completely ineffectual. They are unique to the bitcointalk forum, and not seen in other public forums. I'm a long-time lurker on this thread, but I finally had to make an account so I could start blocking them so I wouldn't have to read their inane babbling.
