you are going to need to cite that. the only accusations of 'sexual harassment' i have seen are asking women at conferences on dates.
And if it is harassment, I'd probably say it's sexual harassment since it relates to unwanted seeking of romantic or sexual relationships in a professional environment.
And why women feel uncomfortable around such a men? And why it therefore might be a bad idea to have such a person in a leadership position?
I have not seen the sign in person, but been told by people that it was indeed there.
It's in the last paragraph.
And I lack the sources, but I recall people saying that the sign was there for quite a while, even if he did not wrote that by himself. And I actually would like a quote from him, to confirm that he did not write it. All that is in that source is someone saying it was not put up by him.
If it was really put up by someone else, it would be the question if it was a joke. Making fun of RMS well known attitude - and he left it as in agreeing, at least for a while - or if it was ammo for a smear campaign. Then it would make sense to investigate that and put it right.
But I actually suspect the former.
