"Last weekend, 3 players were banned for duping specific quest items in Felwood. After the research done by players, it appeared that this bug isn't a major one and as a consequence, cannot lead to a permanent closure of an account.
As a result, those 3 accounts are now unbanned. The following items gathered will be deleted from their accounts. From what we saw of the accounts, some of them already have a "last warning" applied prior to the ban, so please check the Terms of Use and feel free to report any abnormal issues in-game. A log has been applied to monitor abusers and a fix is going to be applied in order to prevent any players from abusing this mechanism again.
Best regards."
tl;dr It's considered a minor bug and future abuse is not allowed.
Question:
Does this also apply to the Songflower buff? Can you tell us how you want us to approach getting this buff?
Cheers. By the way, you handled the situation just fine.
