The kind of research being suggested here would be fine on Wikiversity. All that's needed is to avoid specific criticism of specific editors. Wikistudies are welcome there, otherwise.
A problem has been that some users have used Wikiversity as a platform from which to attack other users (mostly from Wikipedia).
I used Wikiversity, a user page, to document my block evasion on Wikipedia. That page did not coordinate blocking, did not attack Wikipedia (though it could be argued, I suppose, that my evasion was an attack), and did not criticize specific users, it reported responses neutrally. I suppose that someone could claim selection bias, but I did try to avoid that.
And the result was actually positive on Wikipedia. Certain excessive responses were noticed and corrected. A policy was rewritten. It was rare, I think, that a banned user would document his IP edits! Mostly banned users try to avoid detection. So little or no information can be compiled.
There was an attempt to delete this on Wikiversity, by someone who didn't understand it, I think. It failed. But "attack pages" are frequently deleted.
In any case, welcome to Wikiversity, anyone who wants to do original research in wiki studies. Let me know what you are doing, I'm
User:Abd there, and I may be able to help. Wikiversity may be the only WMF wiki that allows original research. It is not an encyclopedia!
