No, not really. If there was some other goal besides the honest exchange of the hat for the money, then maybe. Fraud (“the hats made of gold and is therefore a great value!”) and price gouging (“it’s the only hat for sale on a sunny day so I’m selling it at a 1000x markup!”) might be crimes in some contexts. As mentioned, money laundering (avoiding tax or other legal requirements to move money) is also a crime.
Yeah hard to picture a multi billion dollar studio greenlighting a movie where Spiderman kills the 300 richest and redistributes their wealth, or Iron Man leads a worker revolution.
I think there is an option in Settings. Under privacy there is a toggle for Listening Activity to hide it from followers. It’s below the temporary version of the setting, Private Session I think you are thinking of. Why a temporary privacy setting would be such an option is beyond me.
Always good to know what you are worth and keep interviewing skills sharp. But yeah, you could wait years for a promotion (more responsibilities!) and it only be 10% whereas a lateral move at a new company could be higher pay for the same type/amount of work. Crazy, right?
