Are there cases on the forum when an honest user is framed by scammers. For example, the user participates in the bounty without breaking the rules and not abusing the system of merit and the system of trust. The scammer finds the public key of the victim in the Google table the bounty of the past or in the history of messages an honest user and sends a token with the account, which is also involved in the same bounty. Then he files a complaint against the user from another account and the honest user gets negative trust.
Just like with Merit, the receiving party should always be assumed to be innocent.
Even if there are token/altcoin/Bitcoin-transfers, it could be part of a
Currency Exchange, but there are also
other ways to link addresses while being different users.
This is one of the reasons I don't investigate the (usually very big) threads that link accounts together through Eth-addresses in campaign spreadsheets.
