If he’s still a guildie, why not ask in guild chat? “Hey, who was it I lent money to the other day?” If they volunteer the info awesome, if everyone stays quiet then it could be a) they aren’t logged in (make note of that) or b) they are avoiding you so they don’t have to pay you back. Which means a) you picked a bad person to lend money to, plus if you can’t even remember their name why even lend the money or b) your guild doesn’t have any kind of standards as far as the people they invite in (i.e. thieves, scammers being welcome— that’s how guild vaults get cleaned out).
I have been asking in /g chat for three days now, he hasn’t left the guild and when i asked him how much gold does he make daily, to know when will he be able to repay he said 10/15g per day. So either me lending him money made him quit or he’s just ignoring me. And i know that it is entirely my fault that I didn’t note any of his info, but I was just trustworthy that no guildie would ever scam me. ‘’Never have I been so wrong’’.
Thanks for your help I’ll try to reach out an admin, if he could get me the chatlog from that day. Fortunately I know when he was asking for gold on /g chat.
