Significant value airdrops did not ask for much info or tasks.
These projects stayed true to what 'airdrop' really is. Only asked for the address so they can send you token, tho sometimes there were requirements to prevent sybil entries.
No follow to tens of social links and other social media bs, didn't attach $ value, no sign up, no lucky winners, no referral shite, and oh, no KYC.
Regardless if it requires several tasks or just easy ones doesn't guarantee a worthy airdrop.
Back before, there's no need for social media hypes that's why not much task is needed and sometimes only an address is required to be eligible in an airdrop. But with the dropping value of most airdrop coins, as years pass by, projects need to hyped it that's why they are requiring some tasks to somehow create an awareness.
In most cases, airdrop from new projects doesn't seem to be worth spending time now. It now depends on the self-preferences of the users if they like to participate.
