And now it turns out that he used the interest to help the poor.
Can you explain this better, Little Mouse?
What explanation? It's stated in the OP and there are a few screenshots attached. These are all written in the OP.
Naim027 has claimed the loan was almost free while Mahdirakib has claimed he paid the interest. From the telegram chat, it seems Naim027 didn't ask for interest while Mahdirakib has paid the principal amount + tips (or interest as you say). Naim027 has used those tips/interests to help poor people by buying them some food with that tips/interest. Naim027 has added some screenshots of the cost of those foods (where he spent how much) and sent the screenshot to Mahdirakib.
Mind you, he is not giving loans to found an ethical company, he is giving loans to someone to gamble, despite the fact that gambling is supposed to be a moral conflict with his religious beliefs.
Charging interest is considered the worst sin in Islam. Gambling is also a sin of course. What did you mean by "not giving loans to found ethical company"? I'm sure you have misunderstood some part from OP.
