Need a reddit advice

Hello everyone. I'm a new in reddit "marketing", and still not understand, how reddit decides, who gets shadowbanned. F.e: a couple of weeks ago, when I tried to launch into a sub for which I didn't have enough karma, my post was simply deleted. But now, if I try to do the same (from another account, IP and other browser fingerprints), along with deleting the post, my account flies to shadowban. Does anyone know what the reason might be if both accounts are new, both have quite a bit of karma and in general they were created using the same method? Maybe you should "work up" cookies? Does Reddit even have access to cookies?
