Appeals can be made to the developer in discord. Correcting the situation may be helpful. The rule is also nothing like "new". It was there long before the gift was made - it was in the Terms & Conditions. The change was only to make it more obvious to people since it seemed to surprise so many
Good luck!
Thank you very much, if @efmm has already contacted Discord support, it only made me sad that my friend lost his account because of that gift of starbits, he may not be returning the starbits or giving my account in exchange for his.
