How do eBay sellers getting away with 'aftermarket' bands?

[wowimgod]

As you can see in the pictures, the band is stamped with the Rolex crown, so it's a fake/replica, not just a plain, look-alike band.

"Band: Brand new aftermarket 14K YG President Band"

He also has other listings with 'aftermarket' bands that are stamped with the Rolex crown:

Also this person, "beckertime"; a ton of his listings have 'aftermarket' bands:

THE SOLID 18K YELLOW GOLD PRESIDENTIAL BRACELET WITH HIDDEN CLASP IS IN SUPER EXCELLENT CONDITION. IT IS A CUSTOM ITALIAN MADE AFTERMARKET BAND OF THE HIGHEST QUALITY AND HALLMARKED 18K ON THE INSIDE OF THE CLASP.

If the bands were just look alikes, and didn't have the Rolex crown stamped, I think it would be fine.. but with the crown stamping that's clearly an attempt at a replica + a clear copyright infringement.
