This is just a suggestion to stop the parrot bug being abused, people are openly mass selling gold refills rather than parrot gifts and its pretty obvious they are cheating when you visit them and see their gold mines with 10000+ ore in them.
I wish this had been fixed when it was announced it was bannable months ago, but nothing seems to have been done so far, its completely stopped the trade in none parrot bug gifts due to the difference in gold coin cost.
Stuff like this should be hotfixed fast rather than waiting for the next 1/4 year update to come along.
