In this question the OP acknowledges behaving unprofessionally in the office and is concerned that this may have been witnessed by a female colleague, who is now acting uncomfortable around him.
A now deleted, previously highest-voted answer (even after 20 downvotes) advises that if his colleague discusses OP's unprofessional behaviour, then OP should lie about it, make a false complaint against her, and possibly seek to initiate action for defamation (which would presumably require giving false evidence to assert that her claims were untrue). (Update: that answer has now been deleted as "rude or abusive".)
Depending on jurisdiction, this course of action is likely to involve breaking laws related to perjury and/or retaliation. Further, I would have thought it self-evident that lying and attacking a colleague to cover up one's own misconduct is grossly unethical behaviour... and yet 84 people upvoted this answer. Several other answers also endorsed the same "lie and deny" approach.
I checked the FAQs for guidance on this issue but didn't find anything relevant. Does this board have any policy or guidelines to deter answers that advocate blatantly illegal/unethical behaviour, beyond the usual downvoting mechanism? Or is "cover your ass no matter what it takes" acceptable here?
A related question covers answers that are "high risk to the OP", but my concern here is not whether this advice might backfire; it's that it might function exactly as intended.
