Not everyone believes this crap, copied from AN/I
I do not know either John254 or Kristin Erikson and recently stumbled across this. But, I have to say this looks like a witch hunt with evidence that wouldn't even hold up as circumstantial. They can't prove they're not socks, so they must be. And any evidence to the contrary is more proof because it must have been deliberately planted. If we ban then and they drown, then they must have been innocent after all. Personally, I've been editing Wikipedia since the beginning (late 2001), both as an IP user and with an account that I have abandoned, so I fully understand KE appearing on Wikipedia knowing more than you think a new user ""should". I would bet that the vast majority (like 99%) of users spend some time editing as an IP user before they create an account  the only question is how long they spend that way. It looks like KE didn't bother creating an account until she found a need to do so. That not only is not wrong, it should be encouraged.
Like KE, I have also edited extensively as an IP. For the most part, I found no reason to create an account, but I created a new account recently with my real name and, of course, my new account appeared to be an expert about Wikipedia immediately. Like KE, I also dive deeply into things. Were you to accuse me of being John254's sock puppet, I would do the same that she did  dig into his edit history and compare it to mine to look for evidence to prove my innocence. Most of the contributors here have dug into KE's edit history and now may well know more about it than she does  are you therefore sock puppets too?
Suggesting that defending herself with evidence, against people who are accusing her with flimsy evidence, is ridiculous. And, to argue that she would have deliberately created arguments with herself and other contrary evidence, over a long period of time, just in case anybody ever complained is hard to believe.
At best, the evidence here looks like collusion, not sock puppetry, and I don't even see that. But, even so, there is no rule against collusion on Wikipedia. And we see it all the time, with people cooperating on edits. I personally have emailed people I know to suggest that they edit pages in which I had an interest. Doing so does not make them my sock puppet or vice versa, whether they agree with me or disagree with me. 
To me, this flimsy house of cards rush to judgment and assumption of guilt represents the very worst of Wikipedia, and I think that even if it turns out that they are witches (uh, sock puppets). And I, personally, do not believe it to be true after reading this and the information on KE's page.
