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/addressesStedsm 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.
This is an interesting find, and I do see about 26 linked addresses. This might be linked to more accounts that have not yet been mentioned. It should be about time all the accounts and their links are mentioned and possibly tagged to avoid another catastrophe in the future.
