I imagine they cloak themseleves as a "tutoring service". They know exactly what they are doing. It is a bit like when during Prohibition companies would sell grape juice, yeast, and other ingredients needed to make wine and then put a label on the kit saying "Just to let you know, it is illegal to mix the contents of these ingredients, let them sit for X amount of days at T temperature, and then consume the resulting product".
