Maybe creating a safer environment for creators and cosplayers would be a good place for them to start? Getting harrassed continuously by Kik streamers easily ruined twitchcon for me (which I have travelled to from Australia twice now) and I know so many others as well.
Weird time for a con too.
I pity people that see others doing well and immediately feel the need to say something ugly and nasty about them.
How miserable and painful it must be to live life this way.
