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.
There's not much to speculate.
Fact is that private keys which were supposed to be deleted were seized. Otherwise LE would not be able to move funds.
Based on this one lie from chipmixer, which claimed to delete full session information including private keys, you should assume that they stored all logs forever.
