On a side note, PSA: do not commit your AWS keys into github. Also, now you have the ability to make your repos private. Head over and do it now.
Github was amazing, they detected it, saw that it was valid, and revoked the token. Big love.
On private repos: it would be a sad, sad thing if all those half-baked pet projects went away, there's an awful lot of valuable random stuff in public repos.
