Trying to make sense of it all, it appears marco sold the 2double0 account to Stedsm at some point, probably before BPIP started tracking changes (so this would be in early 2018 or before). Its possible this is the reason why marco decided to "help" 2double0 with their loan issues. I don't think this implicates irfan_pak's involvement other than as another lender who got ripped off.
If anything it's the other way around. As of Feb. 2023 the Steadsm account was still in the hands of the same person to whom I had given the loan, but that's when irfan_pak10 changed the account's email address to one he controls. Stedsm was accepted in the signature campaign and made payments regularly until September of 2023. That was around the last time I heard from him. He either lost his position on the campaign, or it ended, I don't recall. He kept applying for others using my address as we had agreed, but wasn't selected for any.
My suspicion is that irfan_pak10 got impatient and pressured Stedsm into giving him the account, and then sold it to the biological organism also in control of the 2double0 account. Sure, no password change is recorded, but none need be since the introduction of the 2fa feature. Anyone with the password can enable 2fa, and if they are the only ones with the code that pretty much makes them the owner of the account. No matter how many people have the password, only the person with the current 2fa code can log in.
Either irfan_pak10 sold the account to marco, or irfan_pak10 is marco, 2double0, and now Stedsm.
As marco refuses to acknowledge he sold the 2double0 account, he is still on the hook for the repayment of this account's loan, as far as I'm concerned. Although the chance of anyone recovering any owed funds is close to zero at this point.
It is possible that both marco sold 2double0, and irfan_pak10 sold Stedsm to the same individual... But what is the likelihood of that?
Here's what we know for sure:
Marco and 2double0 are connected through old blockchain data
irfan_pak10 held the credentials of the Stedsm account
Stedsm made a post thinking he was logged in as 2double0
irfan_pak10 posted in this thread but didn't refute my claim that he is (or was) in control of the Stedsm account.
Niether marco nor irfan_pak10 are willing to admit that they control or sold the accounts being accused.
