I've had Question & Answer pages removed by the Admin because they were supposedly "better fit for a forum," even though I've totally been banned from the forums, and I've had Hubs unpublished because they were overly promotional even though they only had one affiliate link, and I've had Adverts disabled due to "sensitive content filters," that I later transferred to some of my other blogs, websites, etc. So yeah, this place is a little more strict than it should be and it is definitely different than doing whatever you want on your own websites; ha!
I don't really care, though, as I only publish here on occasions.
Plus, the revenue from the Q & A section is minuscule, if anything, from what I can tell. There is a lot more money to be made via your Hubs.
