How do I get YouTube bots the heck away from my video?

I'm so sick of deleting this comment: Many of us were absolutely astonished that Harry Potter and the Deathly Hallows Part 2 has been already leaked. We all viewed the whole thing at watchharrypotter . us, from my video every single day!!! I'm just peacefully trying to upload some videos onto my youtube channel, and maybe get a few views from my subscribers, and I don't need a bunch of morons spamming up my videos!! How the toothbrush do I get rid of them???
