This echoes my experience. My site (of which the forum was the most active part) was most active circa 2003-2012 FWIW. Our male:female ratio was 2:1. (Which was honestly really high for those days, particularly the early 2000's) Our ratio of problems with male users to female users was probably more like 20:1. Overall it was a positive community. There were memorable exceptions involving problems with female members, both online and offline, but they were notable partly for being such anomalies. Additionally, many female members expressed to me that the "sparring" nature of the forums tended to be a real turnoff. They preferred to use the other features of the site.
