I am only saying that is possible for your actions, though coming from a place of kindness, could have negative consequences.
I can recall a post about some poor shmuck who got cought selling one of the powerscore books on e-bey.
I can also recall a post on LSD from Powerscore, asking people to stop passing around the LGB.
I also think that there is a big difference between giving a book away and passing on a pdf. version of that same book. The pdf.(probably copied illegally or with limited permission) is too easily distributed. I think that this raises the risk factor considerably.
