My idea of ​​
@lineabuild
 airdrop criteria

1. Wallets under 1500 Lxp should definitely be eliminated.

2. Wallets opened only to earn LXP during Linea LXP should be eliminated.

3. 
@MetaMask
  wallet age should be important.

4. Natural transaction numbers on all networks should be high.

5. Network fee payments should be a criterion.

6. Activity on the Linea network should be well examined.

7. Infura usage should bring extra drops.

8. 
@ensdomains
  ENS and 
@LineaBuild
  name should bring drops.

These are my personal opinions. 

People who are not organic with too many wallets will definitely not think so.

Interesting criteria for the airdrop selection process. It's important to consider wallet activity and authenticity to ensure fairness. Organic engagement seems to be valued here.
