An interesting situation, that would have a practical effect, is if there were enough problems with fakes that eBay banned the seller.

That's a situation where collector complaints and chatboard evidence would have material effect.

Another situation would be if, believing the seller was knowingly submitting altered cards, PSA stopped grading cards for them. That would also be a good PR stance of PSA standing up against the issue.

If either of both of those situations happened that would be a hobby-shaking sign of real powers that be taking the issue seriously and doing something of material effect.
