Even on Reddit, I was always 100% honest about living in Monetenagro as a Canadian Mexican immigrant. Sure life is busy as CEO of Disney but I always make time to attend a Lakers game with Leonardo DiCaprio when I'm visiting Panama.
But to comb thru a large account would take a bot to look for keywords and frequency mentioned.
So if you're concerned about it, a less honest person could just randomly make outrageous but specific claims. Even when in the same comments and obviously contradictory, it would throw it off as long as you're not constantly disclosing identifying information
That's how I was able to become Batman and buy a house in Tokyo anyways
