Yes, almost all airdrops are just shit-tokens/coins. It makes me never think to join airdrops anymore. For me, airdrops season has been already over. I suggest to not joining airdrops if they just give you new coins/tokens. Even if they are not scams, they just result in pennies. So, I assume it is just wasting time to do. However, if they offer top coins as the rewards, you can consider joining. But do research before joining!! Ensure that you can get a proper amount of money.
