> The answer is likely yes, as simply addressing it to a single person while posting it publicly in view of many others does not act as the “plausible deniability” air cover you assert that it does.
I'm not talking about wink-wink-nudge-nudge """addressing""" one person. I mean honestly having a conversation with a single person, but it happens to be in a public place.
If I'm walking down the street talking about bank robbery plans with a friend, and a complete stranger that I didn't even know was listening robs that bank, it's unreasonable to call me an accomplice.
> If I post a billboard that instructs “ImaginaryJoe” in how to exploit a weakness of bank security to steal money and encourage “ImaginaryJoe” to do so, and then five other people do so, I will be convicted as an accomplice in all five of the cases against them.
If the billboard just says "Do a fake invoice scam at every bank, ImaginaryJoe!" there is no way the writer is an accomplice to anyone.
