Because there is no way ϟϟ was sent by mistake. This is a character combination that has one use. And is irrelevant to slavic history. And they accompanied it with a kolovrat. This is the guy who invented the kolovrat as a pseudo slavic neopagan symbol. If it was just one ϟ it would be iffy at best, but you know, benefit of the doubt, maybe they copy-pasted a random selection from some random neopagan website. This is the specific combination that has one (1) known use.

The kolovrat alone reeks of neonazism, the ϟϟ is exclusively a nazi symbol, there is no wiggle room
