Seems that I have been scammed by @tawdry finch telling me they are looking for someone to trade referrals with, but they never did so and were just attempting to take mine even though they said they were looking to swap a ref for a ref. As you can see from the pictures and logs, he was explicitly asking around for someone to trade referrals with and said he hadn't used his referral and was looking to do a ref for ref. Immediately after I entered his code, he just ghosted and left the convo. He even changed his name. If you look at name change logs, it was his code which was trapnemic. He removed it from his name and stopped typing. You can see from the chat logs that he was active and typing, but as soon as I showed him proof I used his code, he left.
Is it possible at all to remove referral uses? It's pathetic to be scammed in the first place, but now I am losing out on the opportunity to gain an extra 150 points swapping with someone else. Especially because I will be asleep and miss active quests, and could use all the points when I can. I would appreciate any help with this. Thank you.
