If helping people access accurate info makes me a clown, then I’ll wear the red nose
On the contrary. This app will do the exact opposite of what you said.
Take a look at the UGL section. Practically all the vendors are selling products where both possession and distribution are illegal to their country. Their largest markets are also to those where it is illegal to posses. These vendors are not here to stay for long. That's how you get caught.
The top selling vendor a few years ago, last year and this year are all different. To avoid getting caught, most vendors sell, leave(maybe scam users on their way out), take a break and come back using a different name. Majority of the vendors are here 3-9 months, some longer, depending on risk appetite.
This app will just be full of
(1) Fake lab reports used by vendors who don't want to pay for testing and fake lab reports uploaded by their fake accounts. These can be faked directly by either editing the report document or indirectly by sending good products for testing but sending buyers under-dosed junk.
(2) Real reports by sources, but have left as things were getting too hot. Scammers will take their place by pretending to be selling products from that source, using those real reports obtained from your app.
(3) Real reports by sources, who started of good, then started scamming people and got caught. These sources are still operational but only advertise elsewhere. Showing people their old reports will show that they are good to good, but they are not.
Simply relying on just test reports, with no context or due diligence on the source will just cause people to get scammed. And for those paying for testing, any increased level of visibility results in increased levels of risk, resulting in them being more reluctant to upload any of their tests in future. It's hard to argue that user X who paid $5k+ in testing over the year does not posses any of the illegal products he tested.
Getting gear is actually the easiest part.
Using it safely, is a whole different story.
