Add I understand it, the real meaning of that line is not exactly what it sounds like
As someone who was around at the time, I think people meant it exactly as said. Partially it was an observation that most online spaces were really male-dominated. Partially it was a “no girlz allowd” sign. A lot of places were extremely hostile to women. The best that someone who admitted to being a girl or woman could hope for is a flood of messages from horny boys. That also made it a self-fulfilling prophecy. Girls would either stay away, or they’d pretend to be male just to avoid the drama.
