I don't think there's anything wrong with occasionally shit posting. Especially if you make it entertaining. Hell, there are literal people who have made a career out of shitposting because they did it so well and made so many people laugh.
I think there's a big difference in shitposting, and if you're on the wrong side of it and doing it everyday, then yeah, go fuck yourself. If you do it every once and awhile or even daily but it's funny or entertaining then I'm quite fine with that so long as it's original content.
