I went trough all accounts and I have found only 4 connections(account ZetQ wasn't even mentioned here) and that's it. There is no valid proof of connection(one airdrop/bounty thread was trashed and one spreadsheet is unreachable  )  between these 4 accounts and other accounts mentioned:

Account ZET40 ^^
