How to receive Smog airdrop?

Hello there, I'm curious about how one can receive the Smog airdrop. Could you please elaborate on the steps needed to be eligible for this? I've heard that there are certain requirements and conditions that need to be met, but I'm not quite sure what they are. Could you guide me through the process? I'm particularly interested in knowing if there's a specific time frame or a deadline that I should be aware of. Additionally, is there a minimum amount of Smog tokens that will be airdropped, or is it based on some other criteria? Thank you in advance for your help.
