Reasoning

This group of 21 addresses shows high correlation among them and their transactions on main net and arbitrum and optimism show identical trading pattern.

This group of 21 addresses show close relation among them; their transactions on ethereum main net and on Arbitrum and Optimtism shows identical trading patterns and transfer among each other shows they are sybil attackers. For example, wallet greennfe.eth 0xba07e5cb42cA05D2fc3D96514461D7245050eb7B has directly funded following addresses on mainnet: 0x6Ea6bc1823f6ff7b55Edf80895d053BCd1029b13,0x62D1556564Aca67d7F92c61e1946a02d83255Cb2, 0x46Dd1320B44329DcAb2ce3913F0F43CCfec871B0, 0xe6E2E69030c82aFe3dE8E0E5F3d422ACA43879A2, 0xA3B9Fe8647aa9D7009B9A7Ad1D8D4A2381994eFa, 0x4D184E5198ee0b9d646cd450243DaEbEB6b8cc86 0x21Fa2cf8E56B9938402A7e08703BFBe4Be0943fb. And those addresses would transfer balance back to greennft.eth muntiple times.

Also, many of the addresses show many very identical trade patterns on abritrum and optimism network. For example, on April 1st, 2022 at a time span within one hour, many wallets listed here would mint a ERC21 token Government Token. I have included some of these transaction hashes here: 0xbe20931f663b805358c9ebf0e875247b1ad1736be2b8d511dac5a819f1b2d494 0x3c4d2f5492ee4ee69221b1775164f489508abf2051aa936843f1c5fbd9abe1b3 0xceb5d8f6b854e5c95d2a8dc31fb0e776465274b3b980a154538ac3c58f8dcbde 0x93357a3ac49abbad46352779322454071c6995f1a7cee09c857e34d22c40aaac 0xfdf4c99957a18ea7f31c1159ab9a2e81938c08b169d4c203bb71756718f9f348 0x5be31c7f3139c2bf8f2f28953553c2b7044bf6387b9e4d5bc446e812a6a2ded7

Methodology

I manually checked all addresses activities on Etherum main net and on Arbitrum and optimism.

Thank you for the submission. Unfortunately, this submission does not meet one of the criteria for submissions:

Methodology that has a non-negligible chance of eliminating legitimate users will not be considered

There will need to be additional proof submitted in order to consider this a valid group that does not include any legitimate users. Please consider providing more information about the behavior of these addresses, such as identical types of transactions or similar timing of transactions. Please note that another user that submits an issue with a detailed, non-negligible chance of eliminating legitimate users, their submission will be considered before yours. @Iseeyou23

We have seen a number of OTC deals, NFT direct trades, and friends sending friends funds that connect addresses like this but do not imply a Sybil attack.

Some potential compelling evidence may be:

Please let us know if you can provide this data. Thank you for your work.
