Reasoning

Part1 this address (0x6704e754055f3d6d533461aa4d16af2c02ac99b4) send 0.005 eth to 7 other address at Apr-19-2022 05:07:27 PM To Apr-19-2022 05:33:22 PM All addresses receive funds (on optimistic) and they had similar behaviors

all of them made transcation on (Synthetix: sUSD Token) at Apr-27-2022 12:53:00 to Apr-27-2022 02:10:08 and then transfer ETH to next address eth

Part2 this address(0x88dbfc20d2f2bc004d4dde1947deda4cd478dd0d) send 0.0101 eth to 7 other address at Nov-19-2021 11:45:23 to Nov-19-2021 11:47:52 All addresses receive funds (on optimistic) and they had similar behaviors

9 adresses, not enough 10 or more elligible and correlated check reqs

shanefontaine commented 2 years ago

@Pcoderx

It looks like these might be 2 independent groups of <10 addresses. If that is the case, then this submission is ineligible, as there needs to be 10 or more related addresses. Additionally, some of the addresses would need additional supporting data in order to be considered a Sybil attacker.

I will leave this open and look forward to your response!

@Pcoderx Each group needs to of size 10 ore more. This appears to be three submissions of less than 10. Are Part1, Part2, and Part3 connected in any way?
