Sure, but at least people are sharing information, trying to shut down sketchy drug makers in China putting out adulterated product, teaching basic purification techniques, talking about drugs to stay away from (lots of MXE addiction stories and MCAT horror stories on bluelight). I know a fair amount of people that ingest grey-market research chemicals. I don't think any of them have any illusions that what they are doing is "safe". But then again, alcohol is quite physically dangerous, has a bad addiction profile, and makes people do far more stupid and dangerous things that many more mind-altering drugs. There's lots of people doing unsafe things in the pursuit of hedonism or escape.
As long as quasi-legal analogues and new substances are going to be sold as cheap highs in head shops and adult video stores and the like, which they most certainly are now that more and more designer drugs are being produced everyday, I certainly want knowledgable people sharing their bad, and good experiences with others.
If some people enjoy beta-testing new substances knowing their long-term safety profile is completely unknown, would you rather it be done completely in the dark, or at least with ideas of dosage ranges, knowledge of warning signs of overdose,etc etc.
While it's clear that Shulgin was more responsible than a lot of budding teenage psychonauts, that's not always the case (Lilly's use of ketamine comes to mind), and it's not clear what he was doing was inherently less dangerous. He was often the first person in history to test a substance.
