FWIW, "my" version was intended to be neutral (it says what InIn is trying to do and the criticisms that have been made on LW, and adds that it isn't known how correct either "side" is about InIn's effectiveness) and Gleb has said on the article's talk page that he's OK with it.
It was made in response to Richard Kennaway's post about the edit war, in the hope of stopping it by having an InIn article that demonstrably isn't just promotional puffery. [EDITED to add: that is not an accusation that Gleb's version was just promotional puffery; but clearly it looked that way to VoiceOfRa, and probably to others too.]
So far as I can tell, the wiki weirdness is a combination of suboptimal cache-control headers and the odd way deletion is implemented, and is not a consequence of hacking or other abuse.
I do realize you were trying to be neutral, but it didn't come out that way. The main problem was that the bit discussing criticism was full of fnords; there's no sentence you can put next to "lowbrow oversimplified caricature creepy unnatural offputting" that can result in an overall impression of neutrality.
Richard Kennaway has posted about an edit war on the wiki. Richard, thank you.
Unfortunately, I've only used the wiki a little, and don't have a feeling for why the edit history for an article is inaccessible. Is the wiki broken or has someone found a way to hack it? Let it be known that hacking the wiki is something I'll ban for.
VoiceofRa, I'd like to know why you deleted Gleb's article. Presumably you have some reason for why you think it was unsatisfactory.
I'm also notifying tech in the hope of finding out what happened to the edit history.
