Where can I report Riot?

Your best bet is to contact PAX and complain to them. If PAX wouldn't have a panel that excludes women then they should not allow panels that exclude men.

Jesus please just shut up with that stuff.

This post has nothing to do with player behavior.

women too op pls buff men again

I hear DZK's twitter is a good place to start ;p

Sexist behavior, while unconscionable, is not necessarily illegal, unless it is coupled with discrimination of some kind, or some other illegal act.

Send in a ticket, i'm wondering what would they reply with xD

What did they even do? Odd are, knowing the current state of video game culture and overreacting to small shit, probably nothing serious. Unless you're just memeing or something.

try with media/journals. That's what they try to cater on.
