I have heard one way to prevent a short from borrowing your shares and useing them against you is to put in a sell order for your shares. KXL is $3.40 so put in a sale order for $10. this makes your stock unavalaible for shorts. When KXL gets to about $8. you would then raise your sale order to say $16 or so. I am not a expert either so if this is bad info please tell me so.  I hate the short game as they can beat down the stock on or shortly before options expiration.
