I was for a shor time a member of the forum and discord of Asetianists. There were definitely some practicing occultists there as I noticed some dar ritual being performed occasionaly, that I was influenced by, but not in a bad way, to be honest.
Some of the members were difficoult to go along with, just like in any other community. Though in this case the uneasy members were even in the core of the community, the people that were constantly there for a long time already. That makes it difficoult for people from outside to get used to them and stay. I left too, though I told everyone that it was because of my spiritual path, and I beleived it myself too... later I started realising that I was really not wanting to be around certain people.
Also they have that book Violet Throne, which they all read and study. While I was there and studied it, Iw as visited by astral vamps who tried to drink from me. I can sense that and I can deffend so they ran away without a drop of my energy and never returned.
