There is already a small note in footer stating that this site is no way affiliated with the Github company, i'll make that a lot more visible.
Naming projects and products
Please avoid naming your projects anything that implies GitHub’s endorsement. This also applies to domain names.

Please don’t do these things
Create a modified version of the Octocat or GitHub logo
Appears below the fold in what looks like 9pt* for me; I take it the visibility hasn't been improved yet.
* checked, it's 10px vs 18px attribution line.
>I'm vincent author of GitHub Awards,
Which is the start of one of your other comments is also pretty deceptive. You are the "author of github-awards.com a site that is not affialiated with GitHub"; "author of GitHub Awards" gives entirely the opposite suggestion.
