OP, from my understanding how the forum operates,you don't have a concrete evidence to prove this accusation on both accounts. However,forum members can have more than one account which is not against the forum rules and regulations. It is when the user abuses the accounts by using them for merit farming or joining the same signature campaign with the two accounts, that might be a problem because if you read the rules of most signature campaign, you will see that it is written.
Both are from the same local board.
Coming from the same locality doesn't matter at all,and also sending their btc to Binance isn't any evidence because most people trade on Binance, since it is the biggest exchange. You should come up with a solid evidence before your accusation on WaCthe and Muskp can be investigated.
