Quickseller, marcotheminer, 2double0, and hacker1001101001 all seem to be entangled with each other in one way or another. I'm not suggesting they are all linked accounts, I don't have any hard proof of that, but there several odd things that seem to suggest they may be under the control of the same person.
I think you have a pretty bad sense of finding alts or account connections. Nothing is common between me and all others you mentioned (Quickseller is the most odd part for me), aside of me funding a loan to 2double0, which I found legit as he proved the ownership of his old address to me and I trusted him. This is also confirmed by
Avirunes by verifying my conversation
here.
Instead of shilling this thread with fake connections, you could put your precious time in finding other solid forum spams.
Let me know if I am wrong.
You could be right OR could be wrong!
It would only be cleared at the date of repayment of his previous loans.
As I said, you got a answer to your question from repayment. You could lock this thread now for avoiding fake assumptions as above.
