Share purchase orders

Morning all,

Just wondering if anyone has much experience in short selling of shares, and if so do you think that is happening to S2R on a regular basis?

I ask as I often note persons trying to purchase literally $1-$5 worth of shares for $0.005 under the sell price. I can understand wanting to bring the price down to purchase a large packet however I don't see a large order beneath this small purchase order so can't see any other benefit. This is purely an out of interest question as I am buy for long term and don't play they short term game.

Cheers!
