Hi everyone.

I recently came across a technique that I believe could be used to trigger duplicate content penalties against almost any web site. This could, at least in theory, be used to affect a web site's rankings, either accidentally or maliciously. I would like to open a discussion on the topic to get an idea of whether such a practice would actually be effective, and if so, to try to come up with ways this technique could be detected, prevented, and recovered from.

My dilemma is that in order to discuss this technique, which would definitely be black hat, I would have to give information that would allow people to utilize the technique fairly easily. I try to be careful when describing attacks and vulnerabilities to avoid giving so much information that my posts become instruction manuals, but in this case I am not sure I would be able to discuss the issue without being so detailed.

So, what should I do? Should I post the information about this technique, which might be abused but which we might come up with a way to prevent or defend against? Or should I err on the side of caution and not post the information?
