I voted Yes, because i also think we should mainly focus this to U-graded figures which have been taken from from Moc's or baggies.
I don't have so much of a problem with a brown or plain white mailer box which is opened, as long as the contents e.g. figure in bag is U-graded as as a figure in Bag and not have the bag aswell opened.
The cardback with sliced bubble above is the main issue, that was a perfectly nice moc before, clean card, unpunched, undented bubble (only slightly yellow, but so common on potf).
I don't think the sale of u-graded minirigs or mailers should be banned here, but that my opinion about it.
lets face it, this display's better then a white sealed box....
But i am all in favour for saving moc's and baggies, no matter if its a cut curd or absolute beater.
I once posted on RS, imagine if UKG and AFA stop ugrading, so no extra u-graded figures ever come in circulation again, and then loose figure collecters start buying u-graded figures to crack open to display as loose mint figures in their collections... I guess then the people who collect u-graded figures would be complaining and bitching about it, but yet they refuse to understand now, that they are now doing exactly the same to moc and baggie collectors...
