Something happens and you believe that the products you have are bunk and you feel that you have significant proof. Before jumping out to the world and saying, "Hey I got bunk shit from K and he is just like the rest of those other sources peddling krapp" and other disparaging remarks; why don't you first contact K and say here is what has happened and here is my proof so please give me your side of the story. In other words, get the facts from his end and get his point of view before you rush to judgement. Once you have the full facts and both parties are now involved in dialogue then go ahead and post away about your experience and the facts of what has transpired from both ends.
There are two issues here: One is whether or not it is appropriate to post evidence (regardless of quality) about a source's products prior to contacting the source. The other is making broad conclusions based on limited evidence.
As far as the first issue is concerned...
I and many others here see nothing wrong with publicly posting evidence first. The evidence can stand on its own merit. It doesn't need to be proofed by a source or anyone else. Could this unfairly tarnish a source with a stellar reputation? Possibly.
OTOH, traditional "etiquette" involves withholding evidence from the community for an indefinite amount of time while a source "resolves" the issue. Could this unfairly put the community at risk of harm? Possibly.
Both scenarios have potentially undesirable consequences. Neither is ideal. Which is worse? It depends on whether you take the perspective of the consumer or the vendor.
I think the best compromise is to alert all parties to the evidence in question at the same time. Post the evidence publicly to alert the community. Contact the source so that he will immediately have knowledge of the issue and have an opportunity to address and respond. Allow the dialogue to proceed openly and transparently for all to see.
This isn't unlike what happened in this situation. It is clear that the source was informed of the labmax evidence within seven hours of it being publicly posted. All sides have been represented.
Regarding the second issue...
It's not necessarily a choice between the polar extremes of the source being a swell guy who can do no wrong versus the source being a POS scammer purposefully screwing customers.
How do we evaluate evidence? What can be concluded from limited evidence? Can the results be replicated? Etc. Etc.
I am honestly surprised there is such resistance at the idea of publicly posting adverse products results prior to contacting the vendor or at the same time that contact is made with the vendor.
I would have expected that the "controversy" and "criticism" would take aim at the second issue and justly so: how should such evidence be evaluated and what conclusions can be drawn.
