Reverting for no reason 

I spent quite some time improving an article that was in a poor state.  Now two people have undone all my work with a click of a button.

No-one's that stupid so you were plainly just out to provoke me.  Well fucking well done, consider me fucking provoked.  I guess you didn't even bother to look at the changes before you put all that shit back.

Still waiting for you to justify your risible claim of OR. Also, stop stalking and harassing, eh? 186.9.132.124
