There are several reasons, first the information is out there (outside of BL as well as the archives of the old drug testing forum). Next, the site would be bombarded with the same questions over and over pushing away senior members who give a lot of important HR advice and information.
Next, it most cases the best or *only* answer is just DO NOT USE if you have a test. Its pretty simple and we don't need this shit.
There are more reasons, I just highlighted some of my favorites. Next time PM staff, don't call out BL rules publicly.
