Hey All
I have no idea what to do. I have been asking around. Hard spaces are being adding to English Wikipedia by the 100s to 1000s. I have no idea why and I have no idea how to fix it.
I have brought this up here https://en.wikipedia.org/wiki/User_talk:WhatamIdoing#Hard_spaces
and
https://en.wikipedia.org/wiki/User_talk:Cacycle/wikEd#Stop_adding_%C2%A0;
Folks appear to be saying that the problem is someone elses problem. It appears to be mainly coming from education initiatives / those who use visual editor and thus I imaging copying and pasting content between different parts of Wikipedia.
