I didn't investigate the possibility of bounty managers manipulating the spreadsheet data of bounty participants. But I see at least 3 names you mentioned are alts connected to transactions.

you can see this transaction: https://bscscan.com/address/0x0bc4d4ceeccc9c9f6b426360c38b5afed3bcbcb3#tokentxns
all three addresses send BUSD to one address.




If this is proven to be manipulation by the manager, it is possible that the manager included several alt accounts in his own campaign.
