Same problem here... slack user name not on the list and no airdrop. I found my email user name. Hope this gets sorted out quickly.

I can appreciate why this is a concern for everyone. In this case, since all the payments have been made, we are not able to make any additional payouts for those that missed out on the airdrop. I know that this is not the answer that you were all hoping for, and for that, I apologize. Slack Usernames are not the same as your display name. In some cases, when adding a name from Slack, some users provided their display name rather than their username. When we did our search for this information, and it could not be validated, it resulted in a no for the airdrop. Again, I know that this is not the resolution that you were all hoping for. If you have any additional questions, feel free to reach out to me.
