ChipMixer boldly promised to delete all logs, don't keep confidential information and don't store private keys of payout Chips. It lied to everyone.
Unless you are somehow privy to information the rest of us don't have access to, it's yet to be established that ChipMixer kept logs. We know that data was seized, but people are merely speculating on what that data might be. If you could try fo keep any accusations you might wish to make
evidenced by verified information, that would be appreciated.
I reckon all web servers keep logs, temporarily or permanently, for different types of reasons. It would not be shocking for Chipmixer to have kept 30 day logs for customer support reasons in case something went wrong with the user's transaction with the mixer or because of other technical reasons.
Also, if there was 7 terabytes of data taken by the authorities, how much of the data are logs and what other types of data do mixers keep?
