Yes many people following the airdrop channel. Every airdrop is full of participants because it's easy to do. But i think for current time, the rewards from airdrops is not worth it because many airdrop tokens have a little value or even have not value at all, eventually just becoming a shit coins. But there is no harm if you want to followed it  because the airdrop procedur is easy to do, after that you only waiting for payment. It's not takes so much of your time.
