Yes. Person-A was in an online forum I was part of. Person-A said to Person-B, who was getting emotional in a discussion, to not act emotional, as it was a factual discussion. Person-B accused Person-A of being insensitive to women, as it turns out Person-B was female. Person-A did not know Person-B was female, as Person-A didn't use forum avatars, and the name Person-B used wasn't an obvious female name in Person-A's culture. In other words, Person-A could prove not knowing the gender of Person-B. This was not sufficient, and Person-A was banned from the forum. Ironically, Person-B was one of those loud "women and men are as competent as each other" sorts, which leads one to wonder why she needed special handling. The icing on the cake: Person-C defended Person-A, knowing that the gender of Person-B was not known at the time of the comment. Person-C was banned from the forum. The forum, by the way, was a professional forum of one of the largest tech companies. Everyone here would know the name of the company, and being banned from this forum essentially was a light way of getting onto a blacklist of several other tech companies. This actually eventually led to Person-C quitting technology entirely a year or two later.
