I forget where I got this, but it somewhat explains who ad0 is (not necessarily what he did, I don't really agree with the reset stats part...)

Ad0, the guy who hacked Neopets
There is a real hacker/cracker among neopets. He goes by the name Ad0. If neopets is the Matrix, then he is "the one".
Very little is written about Ad0 because Neopets doesn't want you to know about him. I myself am not Ad0, nor do I know him, but he does exist. One time around mid-2003, you might remember reading in the "Neopian Times" about a mis-firing lab ray that was destroying pet's stats. That was a lie. It was Ad0 who caused it.
My friend was there, and saw it first hand. Ad0 made a script that reset and lowered the stats of everyone who posted a message in the Battle Chatroom that day. And for good measure, he reset the "famous" players accounts, of featheralley, v_team (when neopets still liked him), etc. We all know Neopets has favortism, meaning they "favor" certain players over others, they help out the players they like and screw over the ones they don't. When Ad0 hacked neopets and changed pets's stats, of course they restored their favorite player's accounts.
However, for the thousands of other players, they simply did not want to, or did not have backups to reset those players' stats. Pathetic. To cover up the perpetual lie that "neopets was never hacked", they had to say something about these thousands of players who's pet's stats were suddenly erased. They blamed it on a "mis-firing lab ray", even though lots of the players who had their pet's stats changed didn't even have the lab ray. Just more lies from Neopets.
This was not the only time Ad0 hacked neopets. He's been a thorn in their side for a long time. This is the only time I had first hand evidence (my friend was there and saw it happening). There are more stories . . . but don't dare mention "Ad0" in neopets. The staff will freeze your account just for mentioning him . . . it's all part of their web of lies and cover-up. They ban free-speech and criticism of neopets is met with punishment of neo-death (freezing your account).
So yes, neopets was hacked. And when they do go down for hours and hours or even days at a time, you have to wonder. Are they "upgrading" or are they just "being hacked". Was it really a "glitch" . . . or was it a hacker. A hacker like Ad0.
