Bots clicking on my links

Hi, is there any wp plugin that stops bot by going thru my amazon affilate links? Stats on amazon are confusing me with all these fake links

Thx

depending on what bots they are, you might try using javascript to open the link instead of using the href.
most 'stupid' bots don't support javascript

but others use real browsers and will support javascript and i can't think of a method on the top of my head to block those

and ofcourse, use robots.txt for spiders etc

i also thought about the robots.txt, but i dont know what to add inside that file.
