Dont quote me on this. I believe they are different "bugs".
I believe the new stolen drops, you could sell them to a vendor and then recieve them back as the old server birth rare tag.(im guessing its the same base ID)
The one this is, is a bug. Which should and probably will be fixed soon(as its not the same art as the server birth i think poeple would always be dubious of it if buying).
The first is an exploit the second is a bug. IMO people should never be banned for finding/using a bug. People should be banned for using an exploit.
Honest players should report a bug, however we all know they wont
My opionion anyways
