Ask HN: Bot Posts? Arrington - This is why we can't have nice things.

A recent post by pg stated: http://news.ycombinator.com/item?id=2404916 > Ids are sequential, so there's a time machine at your disposal: > http://news.ycombinator.com/item?id= I've been slowly working though them from the start to see how HN looked at its earliest (before I joined, and even before I started lurking). In the first 250 ID's there are tons of posts from usernames "Arrington" and "M_Arrington" which simply read: > This is why we can't have nice things. Most of them are marked [dead] so you'd have to have "Show Dead" enabled in your profile to see the posts. The endless number of repetitive posts were obviously done by a bot (most likely trying to prove a point?). I did try to search for the answer before asking, but didn't find anything specific, so I was wondering if anyone could give me some more insight or background about them?
