It is IMHO not a principal difference, but only a difference of nuance.

You see, I hold the opinion that your entire argument is on a sliding scale.  First we ban the naming of brands of solvemt, allowing only desciptions like "naphtha".  Then we ban the naming of type of solvent, allowing only "non-polar".  Then we ban explicit teks, allowing only vague references to "acid-base extraction".  Then we ban mentioning plant sources.  Then we ban the word "DMT".  Where does it stop, I ask?  Do you want to make DMT a secret?  Turn the dmt-nexus into a closed site, inaccessible to google and the rest of the proles?  Realize that you would not be here if it were so.

There were specific reasons for banning the naming of sources for dried plant material.  These reasons do not implicitly transfer to sources of extraction tools.  You have to make a good case about it and I think that you have not done so. 

I have asked you a couple of times for proper arguments and you have not provided these as far as I can see.  You claim that shops discontinue sales of some products because of their use by home extractors, but when I ask you to provide fact and reason, you ignore my requests, but reply by accusing me of making mental backflips.  I think you can do better than that.
