The posting guidelines are below. It always pops up when someone posts. I don't see "investing" and "politics" mentioned here. Where some of these mystery shopping topics ultimately end up discussing somehow. So I don't know what the guidelines are regarding that. As long as that stays in General Chat, it seems to be fine. It seems like everything is loosely moderated.
