Both WatChe and MusaPk may be alts of each other, or they may not be, but the evidence provided here in your post is not enough to proof them that they are alts.
Sending payments to binance is not an issue as many people would be doing the same and we could not say that all of them are connected. Having them belonging to the same local board is also a vague argument. Finally, by comparing the writing styles in his manner seems like you wish them to be declare them alts while they are not.

Better come up with more solid evidence and do not create account for the purpose of damaging anyone's reputation.
