I think it would be cool if Twitch partnered up with a breast cancer research charity and If users donate to charity through Twitch they could unlock a pink ribbon global badge and maybe some emotes. I think adding a badge could make it easier for users to find out about these charities and if they donate to it through Twitch they can be sure that the charity is a legitimate foundation.

I'm not very good at photoshop but I made a concept for the badge.
