The answer's disclaimer currently reads as follows (emphasis original):
In some locations, it is a crime to provide certain types of false information to a potential employer. If this is the case where you are, or you are not sure, you should consider Eric Lippert's Answer. Otherwise read on:
Honestly, I don't see why you want to delete an answer that has a well-phrased, well-integrated, strongly-emphasized warning of its potential problems and the circumstances the warning is applicable in. What more could the answer even have to avoid leading folks to try risky things? For that matter, it would not be hard for someone to think of this on their own and try it, without necessarily being aware of the serious problems. So wouldn't it be more dangerous if any mention of this particular approach (and its dangers) was purged?
(I also find it very troubling that you're even considering deleting an answer you think "may be the ethically correct thing to do". Trying to talk someone out of doing what's right because they might suffer quite a lot would be bad enough, but outright concealing the possibility from them so they don't have an informed choice? That's messed up. Why would anyone want to censor information or arguments they believe to be correct … unless they think something else is more important than mere ethical correctness?)
