I've heard mixed comments about this working or not to combat brokers lending your shares to shorters. I guess it doesn't hurt to try, but in my experience, you can't put a sell price extremely far above the current pps. I can't say that's how it will be with all trading platforms, but I had no luck with Scottrade and Choicetrade. I guess if you can, it doesn't hurt to try, but it's one of those things where a ton of shareholders would need to as well.
