A general point about books and materials, sometimes if they are not too damaging to people, they can be sold or traded.
For example, a friend had hundreds of flakey New Agey books, and they took them to 2nd hand bookstores, and got some cash, and good books on science in exchange.
They got back hundreds of dollars, which is better than nothing.
But for dangerous cult books, that can lure people into a cult, one can't imagine those should be sold or given away. They are a toxic poison pill.
A shredder for recycling, or a ceremonial campfire might be better.
It can be therapeutic to make a ritual of getting rid of that garbage, and not infecting others with the toxic material.
But if someone has a valuable piece of furniture, or something that is neutral, then why not sell it like any other piece of furniture using ebay, craiglist, or something like that?
As far as getting out of a database, that is possible. It takes work though.
Someone once signed someone up for a type of religious cultish group that "prays for you" and sends you prayer cards you never asked for. The member pays each year, and then the group sends the non-member cultish prayer spam, and "prays for you", as your name is on their prayer list.
This person got very offended, and called their head office many times, and got through to the person in charge, and got them to confirm in WRITING the name had been deleted from the "prayer spam" list. They took it off.
Its like the Mormon's putting everyone on their list, without your permission, including people from other religions. [

That is extremely offenseive, and its possible to get off those lists, but one has to really make some noise.
Of course SGI will lie and say you are off the list. But a person could research the rules, and demand written confirmation from SGI that the name is out of the database.
It can be quite therapeutic to be assertive.
But of course, one has to be careful, the SGI experts can lure some people back into SGI with any personal contact.
