I 100% agree with Bambu’s decision on this.
I made a mistake a few times downloading on another 3D printing site assuming a print would work then after printing realized the person didn’t make something printable at all. I now know to confirm, but it is much better to be able to assume that a model on a 3D PRINTING site is actually printable.
Better that the person posting the model spends their money making sure it is printable, then multiple people wasting their money for filament on models that are not printable.
