The airdrop turned out to be very weak; many users were dissatisfied with what they received, so no one is waiting for a second airdrop. The project had a good hype and was listed on many popular exchanges, but there are not many projects working on the Sei network and this is a problem at the moment, more scalability is needed.
and yes if this is their attitude then you should try to prevent from Joining not paying airdrop.
though they have paid but I believe that it is not enough to what you guys expected?
maybe try different approach and chooses to join relative company to pay you better, this is also the reason
why I am not joining airdrop nowadays because of those attitude to not pay for our efforts.
