I'm responding to requests at Stewards' Noticeboard, which seem to have been missed inadvertently, and noticed this request BhanuSrivastav for deletion of the wiki. I confirmed that BhanuSrivastav is a bureaucrat on the wiki, along with Shaunak Chakraborty and Gyaanimedia Foundation—the latter has made no contributions or log actions and the former two of not contributed since April.
I checked to see whether there was already a Phabricator request for this, but only saw a previous request from last year requesting deletion of another wiki. No idea why they seem to be creating and deleting wikis. o_O
Anyway, I'll tag the post as tracked in Phab.
