Yes, agree, and I have volunteered countless hours to helping members of this forum buy only authentic Hermes bags. And for now will continue to volunteer my free time. But this is not a one size fits all template.
It is pretty obvious that there is no one approach that makes sense across all the multitude of designer brands authenticated on tpf. This is shown by the different approaches expressed by different brand authenticators. The variation in price points alone is enormous. Authenticating Hermes bags is not to be undertaken lightly. The dollars at stake are considerable. There are extremely sophisticated fake Hermes bags that have deeply penetrated the worldwide market. Very few members, even those with over 500 posts, are qualified to authenticate an Hermes bag, or would even want to voice a public opinion for another member to rely on at this kind of dollar level.
In Hermes we don't do private sales, because we found that our authentications were being abused by many sellers seeking validity for their items for free. Let alone the posts with stolen pictures and lack of verifiable listing provenance which could have resulted in fraudulent market offerings being given verification without intent. The examples were endless. This won't change. That makes sense in our brand based on our extensive experience. Authenticators for some other brands like Chanel feel likewise, based on their experience in their threads.
If an Hermes bag is for sale publicly then an active member has plenty of opportunity to ask for authentication before entering into a contractual obligation to buy. This is one reason we don't authenticate closed Hermes auctions. If someone does buy a fake for whatever reason then they need a professional service to do anything about it anyway. Opinions voiced by volunteer authenticators on threads on tPF have no validity with PayPal, eBay or a credit card company in a dispute about a fake bag already purchased on eBay or elsewhere.
People read the authentication threads because they know they are getting reliable information. This accounts for the high traffic to those threads and resultant good metrics for tpf. The disorganized situation in the threads where established authenticators have quit is unfortunate for the forum public image, and I am sad to see it.
