I was checking the maps for my area and noticed that many of the unsurveyed streets had been changed from highway=road to highway=unclassified. I have contacted the editor and requested clarification on the edits, but have not received a response yet (request is only a few hours old). Meanwhile looking at the other edits done by the user I have detected edits done in other countries of the same type, hundreds of them. You might want to check your areas for the same kind of edits.
Assuming I do not get response from the user and a reversion needs to be done world wide what exactly do I do and who do I contact?
I am not naming the user because I am still waiting a response.
Oops I posted this in the wrong forum, can somebody move it to the correct one. Sorry about that
