The entire premise of this study is not useful, because what you're asking is "what is the numerical occurrence of quantifiable harassment" and not "what is the rate and which players abandon playing the game as a consequence of feeling unwelcome and how does it vary by gender". What do the numerical rates of harassment tell us, and how are they actionable? If a group of players does not play because they feel unwelcome, THAT is the thing that matters, and your study does absolutely nothing to analyse this criteria.

> I avoided ever using voice chat and would call things out in text chat when time permitted.

Again, this betrays a deep flaw in methodology, since voice chat is an integral part of competitive Overwatch. The important things to consider here are: what percentage of players are comfortable using voice chat and how does that vary by gender; does availability and usage of voice chat confer any competitive advantage to the player; and do the two factors interact in such a way as to confer a competitive advantage to one gender over the other?

I find it disturbing when men do scientific studies to determine if women's stated experiences are real.
