ahimsaHave you checked out @alttexthalloffame ?
Edit to clarify - not a contest but an account that celebrates well written alt text and also posts tips on how to write good alt text.

Thank you for the shout-out!
I also briefly ran the #AltTextChallenge -- also not a contest, rather a community exercise to inspire people to get creative, and thoughtful, when sharing images online.

@theplaguedoc @ahimsa_pdx @profdc9 It's on hiatus right now, but definitely thinking about resuming it!
