According to Foresight News, LayerZero co-founder and CEO Bryan Pellegrino responded, "If you can ensure that the witch addresses are not shared with other projects, I believe many people will voluntarily prove that they are witches." He said that the list of self-reported witch addresses will not be published, "All addresses will be included in our own filtered witch list (ie, ineligible for bounties), but will not be listed as self-reports."
Foresight News reported this morning that LayerZero has launched “Self-Reporting of Sybil Activity”, whereby self-reported Sybils will receive 15% of the expected airdrop allocation.
