Riot IQ website/application possible security vulnerability

Dear Riot IQ Team,

The Riot IQ website/application leaks user email addresses. Currently, this concerns around 200 addresses.

The addresses are shown (included) in the HTML source of several (all?) www.riotiq.com (and, previously, app.riotiq.com) pages.

Demonstration: search for the string "whitelist" in the HTML source code of, for example, https://www.riotiq.com/ or https://www.riotiq.com/app/auth.

Please fix this issue as soon as possible.

Thank you,

An anonymous riotiq.com website visitor (NOT being one of the current private beta users)
