It's not Yehuborim. Where is the evidence that it's Yehuborim? ONA, like JoS is National Socialist and rejects everything Abrahamic in relation to Satanism, like their Qliphoth and Yehuborim grimoires. They also define Satan as the Enemy of the Yehuborim.
Their methods are misguided and dangerous, but they are not in any way related to Yehuborim.
Yehuborim "Satanic" organizations are the opposite of ONA: they are against National Socialism (and often promote marxism and communism), they glorify Yehuborim and they sometimes falsely claim Yehuborim are "Satanic". I ran into such a group in the past, where a self-proclaimed "Satanic" High Priest in his Yahoo groups banned everyone who attacked the Yehuborim using the excuse that "we are only against the christians and Yehuborim aren't christians".
