User blog:ArtisticLoner/Editing

I've been having a problem with editing on this wiki. When I add information to the articles sometimes, someone will undo it, but never write why they did it. I wouldn't want this to happen to the other contributers of this wiki either. I was blocked for this twice. I wrote this on a blog in that wiki, but someone warned me I could get blocked for it? Does anyone have any idea how to confront this peacefully?
