I wasn't trying for any gotchas, my point was -- and remains -- that in this case the word "improvement" is likely to be understood differently by different people.
I am not passing any moral judgments or making insinuations about anyone's character.
By the way, if you're aiming for accuracy, the verb Gleb used was "cringe". You chose to render it as "reluctance" which, I think, also changes the flavour albeit in another direction. It's up to you to decide whether cringing and still writing "would reflect negatively on his character" :-P
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.
