Ok yeah, I have dashboard access and everything.
This is BAD.
different account pages have me logged on as different people
When I go to the homepage, I'm logged in as ogsZyphent, whom I've never heard of. If I go to any channels, I'm logged in as myself.
This is potentially a huge fucking issue, given that Twitch has my credit card information.
It doesn't look like you can actually do any damage. Worst thing that happens is you see the email address of what appears to be only 2 accounts.
