They basically rely on mob rule; if enough people report you for whatever reason, you will eventually get edit-blocked or banned.
Quora management is probably one of the most frustrating systems to deal with.

The fact is I have 3 reports in 3 years and wasn’t edit blocked because of them, i got no official email saying that I was removed form the partner program or exact reasons about this and the edit block. I got only one in app notification that said ‘You are temporarily edit blocked: Fraud in the partner program’.

Right now I’ve contacted the European Commission asking for help and I’ll se what I can do, because I didn’t lose only the permission to be active in the community but money of my hours spent doing what they asked me to do.
