It is. I even did it briefly a few times when claims were brought against me until things were sorted out. In one example, an attractive and persuasive woman sent a shit-storm of rumors and claims my way through various parties that I quickly traced to her. Fortunately, the people (including women) who knew me were able to spot that they were bogus since the good and bad of my style is well-known. Genuineness occasionally pays off I guess. And the claims didn't fit it.

Further investigation confirmed my counter-claims that she wanted my job and the next promotion after it. Instead of outperforming me, she decided to simultaneously create situations where I looked unfit and sexist with rumors and a clique of buddies backing it up. They'd benefit if she was promoted. She never got fired like the guys do in similar situations in that company but did back-off and quit after upward-movement was cut off.

I agree it harms both genders. Work was never fun during any of these situations as people started practicing self-censorship. Not just me or the men. It's why I fight such non-sense and Codes of Conduct that facilitate it, too. Fortunately, each event was taken care of, people became themselves again, and work went back to productive and fun. Cuz real people are more interesting than fake ones. :)
