In this case, it's easy to predict how LessWrong is going to react. Your initial posts were well-received because you pointed out a potential problem, LW's high bounce rate, and even created some nice graphs. But when a consensus started to emerge that reducing the bounce rate would actually be a net negative, instead of accepting this or refuting it, you made a long series of posts mostly reiterating the same unconvincing points. Doing that will result in a poor reception.
