Deleting this thread or even changing the topic title is not a good solution. Such discussions are good as a reference for future scam prevention, and it is always good to have such information.
although there are services for saving unedited posts (loyce.club and ninjastic.space), many users do not know that they use them or even do not know that such a possibility exists. The topic can be locked, but the original post should not be deleted.
I agree OP is selfish if he got his money he can change the title to resolve the reason why we are creating accusations here is to warn others so if there is a scheme or online platform that's scamming people, we should let other people know it to avoid that platform.
We can't blame OP maybe he was asked to delete the thread in exchange for giving his money back, anyway the post was quoted so it will still show what happened.
I hope others who will open an accusation should not delete the thread, adding the word Resolve is already good.
