Here's an idea - rather than trying to trick other webmasters, either don't use recip linking and focus your efforts on other types of links - or only recip link when it makes *sense* regardless of the engine algos.
That's exactly right. Focus on other types of links, and only do recips with related sites that offer great content that you do not... period. The key is one-way links, and you can get them by paying for them or by writing articles and offering them to other sites in return for leaving links to your site that you embed in the article in place. That works very well!
