Just out of curiosity, how do we know that what is in the Wikipedia comments is accurate? I have no skin in the game. I was just wondering. Anybody can post anything on Wikipedia comments. I find it odd that Ars Technica would use that as a source. Maybe it's fine for gossip and speculation but it shouldn't be in Ars Technica then.
And you obviously have no reason to believe me, but I was following this when it was happening at the start of this year and can confirm that the DDoS script and archive text replacements really did happen.
