Many women for instance I know pretend to be men in these online games. Often the only people screaming and utilizing voice online seem to be of a specific demographic.
You can go after the bad apples and hope things will change but racism and all sorts of hate based ideologies are constantly touted by what I presume individuals with a lot of idle time.
I also see lots of talks of depression and mental health issues in the chats. I rather that they just remove the online chat feature and custom banners. Remove voice chat especially.
Really miss the days before voice chat because now its the equivalent of giving a village idiot a megaphone.
