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.
