Zarove Arbitration

Hi, I'm working on an evidence entry, and have a couple questions. 
How much time do I have to add evidence? How long do these things normally take? 
Is it acceptable and/or advisable to mention Zaroves history on other websites? 
Zarove has made numerous claims about himself, some self-aggrandizing and conflicting, and some just plain disturbing. Would it be at all useful to bring any of this up? 

Also, FYI, I recently posted an  on my user page.
