Obvisouly for the free tokens, but other than that, what else incentivise you taking the time to do the airdrops? Most of the time, I found that the airdrops often give little to no return. I just started to get into the crypto thingy. I feel like it is better off finding those ICO projects and considering investing in rather than chasing like 5 dollars?
You made the right decision and I encourage people reading these posts that they do the same, these airdrops are worth nothing and if ever they will have a value it will just worth $1 to $10 and this is in exchange for your personal info it's like you are endangering your identity online for $1 so better think and stop doing airdrops from now on.
