Actually, it was my fault that I had not checked at the time of lending the money to them. All of the mentioned users use part of the same account, the Bitcoin wallet. You can check it at https://www.walletexplorer.com/wallet/013184bb1458a768/addresses

Stedsm and the main defaulter of my loan are the same people as the monthly interest was paid by the accused person but posted by Stedsm but later stedsm deleted that and the same content posted by the accused. But I did not know about other and while I checked bitcoin wallet I found all of these. And I think there might have few more users who are the alt account of the accused.
