I am not sure there is agreement about the direction of improvement.
Gleb has posted how he finds it difficult to write sleazy scummy content, but overpowers his reluctance and through great personal sacrifice does write it. I would expect that "improvement" for him means more concentrated snake oil or, perhaps, less personal discomfort with producing it.
I don't think this is what Elo would consider "improvement".
that sounds like 2 not 1. yes. Now what (should be done)?
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.
