I have no stake in this story, but how could you, or anyone, possibly know that?
But I also have no stakes here.
Are you sarcastic? This is logically a very useless statement due to the nature of trust. Once trust was broken it’s hard to obtain because does clearly lied about other things, why should he be trusted now that he’s been caught.
“I’ve been remarkably open about all the extra marital affairs where I’ve been caught, please trust there are no others.”
“I’ve been remarkably open about all the robberies where I was convicted, please trust that there are no others.”
Etc etc.
I would feel foolish even presenting any unsound logic and can’t even think of a situation where it would be relevant to trust. Officiated lie detector? Sodium pentathol administered by an adversarial government? Testimony under oath?
If you have extra marital sex right in front of your spouse, that is no indication that you are hiding secret affairs.
If you walk into a police station and tell them you robbed the bank across the street, there is no reason to believe you have secretly robbed many others.
I don't like reddit, and I don't like spez for other reasons (downgraded from Lisp to Python), but what he did was literally just a harmless joke. All reddit posts and comments are publicly archived by services like pushshift; we'd know if they had a habit of doing this.
