Not VMP, but I had a record for a Christmas gift definitely opened and very much haphazardly taped shut about a week ago. I assumed customs is definitely fucking around with it.
What's actually crazy about it, is that it was a discogs order, which usually get sent through with zero customs - but this one had a price tag on it, and I think customs saw this, and then decided that they needed a cut so slapped a $20 customs fee on it.
My conclusion is they're now trying to check invoices/price tags and then ramming you with customs, and because VMP orders do not come with any invoice or price, there's nothing they can do about it.
