Why do you feel the need to make known your gender online? It is well-known by now that we live in a patriarchal bigoted society that hates women, period. This is not up for debate. Misogyny is ubiquitous, especially online. So, simply don't advertise the fact that you're a female. You will suddenly find that you aren't receiving the same bad treatment as you are surely accustomed to by now. No more perverts creeping on you, no more discrimination, etc. You have only yourself to blame if, knowing the way women are (mis)treated in our society, you choose to present yourself as a woman online; essentially, the only place where you have the option not to.

On the internet, there are no women. If you advertise the only attribute that you see worth mentioning, then it is by your own doing.
