For years now, shabunc has been a disruptive, trigger-happy moderator coming up with the pettiest of excuses to put questions on hold or straight-up delete them.
The examples are too many to list, but so far, for each of them, one could at least theoretically give him the benefit of the doubt. The rules of Russian SE itself are written in such a way that one could quite liberally wield the ban hammer and always find some rule to quote. Then it would become about the question of whether it's beneficial to apply the rules this rigorously, which I've always maintained it isn't, but I realise it is a matter of opinion.
Not this time.
Here is shabunc either showing a basic lack of competence with regard to this SE's subject matter, or else taking his petty fault-finding to an absurd level. It's obvious that a "Russian IPA letter" means an IPA letter for a sound in the Russian phonetic inventory. One could maybe argue there was no prior research shown, but that was not shabunc's stated reason for putting the question on hold. Nor is the question too broad; all it takes to exhaust all possible senses in which it was asked is, describing the sound represented by the IPA letter in question (ɵ), and adding that it's an allophone of /о/ between two soft consonants. The latter is not something the asker would necessarily be told at Linguistics SE, where shabunc proposes to ask it instead.
This is not a one-off; this is not even "the usual"; this is a clear and frankly embarrassing abuse of moderatorial powers by someone whose quite apparent enjoyment of restrictive moderating has been tolerated here for years.
I would kindly ask not to be tone-policed — I've tried being nice — and I would really hope that, for once, Meta will not be this barely visible place where issues peter out quietly.
As a moderator, shabunc is a liability on this SE. I don't know him personally at all; I appreciate his legitimate and useful contributions both as replier and moderator (albeit in the latter capacity, his legitimate and useful contributions have been somewhat few and far between). I ask others to speak up, and I'll be completely fine if you speak up along the lines of "Nikolay is strangely and obnoxiously overreacting but he kind of has a point". The important thing is, we can and ought to do better than this.
