@Annu2047 We have observed cases of apps sending funds through Disperse to help their users pay for gas on L2s. We have also seen altruistic people and faucets do the same. Because of this, we will need additional evidence. Some potential compelling evidence may be:

  • Identical transactions on the exact same day/time by most or all of the addresses
  • A trace of the ERC20 token between addresses (as opposed to native tokens)
  • A similar time/date that all the addresses started transacting on a chain

Minting an NFT within the same day is interesting, but does not provide conclusive evidence of a Sybil attack.
