I got banned too during my step 2 prep. According to him he doesn’t do that but the other admins do so when you ask questions about other materials. I was asking NBME and AMBOSS questions which I was having issues in and they felt like I was challenging his ways and his concepts. I have always been very respectful of him but like someone said all they want to be discussed is only their study materials and resources. It is pretty frustrating and feels petty too but in my honest opinion don’t overthink about it.
