"Quick announcement to all my subscribers: A few days ago I was removed from the Warframe Partner program due to an NDA leak.
The full details are on my Discord channel for those interested, a more TL;DR version is on my twitter.

As a result of this removal, all remaining unclaimed glyph codes have been voided, and I will no longer be able to give glyphs away to you guys on Discord or in my video descriptions. I sincerely apologize to you guys, as my dumb actions means that people who want my glyph will no longer be able to obtain one. All existing glyphs will remain in-game, so those who have already obtained my glyph will not lose it."
