I'm not a writer and I make up shit all the time on anonymous and semi anonymous comment threads. It depends on my mood and the atmosphere of the thread. I avoid it here because I have some sense that this is an "adult" place to be where common sense opsec is reasonable but I don't have to invent anything to fit in or comment. On reddit or other such things though, hell yeah I'll drink a pitcher of Miller Lite while watching a football game and shitpost the devil's advocate or contrarian position under a pseudonym with no attribution. I justify it by calling it social research.
