That's a fair point to make and I believe I probably stand corrected on that point. Nevertheless, it doesn't seem like a self-selected study (particularly one with a heavy Australian slant) is a particularly good one for this kind of topic. And I think that 68% of the participants being women probably indicates that self-selection might not be the right model for this study right off the bat given the probable nature of online trolling.
