Not sure man, i felt bad for missing ENS airdrop, so thought of being alpha and search for a new one lol.
But i do get what u mean, often time these airdrops wont worth much
You will not get that much in 95% of public airdrops l, better do you bounties on forum than wasting time on useless tasks for worthless coins. The free airdrops also collect data and use the free data mining. Usually I pass such offers and look for gem altcoin investments rather than hoping for good airdrop.
