Assuming they really are heretical books, what’s the law?

Same as above.

I haven’t bought the trilogy, but if these really are “sex books,” I’m very interested and willing to pay double for them too. Are there pictures as well?

Doron,
I didn’t know you were that desperate.

That’s common knowledge.

Careful, ISIS-types ahead of you!

And speaking of one thing leading to another on the same subject:

What do you call someone whose checkbook fell out of his pocket? — “Minus books are dropping from his pocket.”

A practical solution for the future: buy the digital version.

In the book ‘Gate of the Courtyard’ it brings the prohibition [that has been forgotten?] against taking books out of the Land of Israel to abroad.
Bottom line, it’s forbidden.
If so, the one who burned them so they wouldn’t be taken abroad prevented a prohibition. And he was performing a commandment, and a person is pleased that a commandment be done with his money. If so, there’s no basis to sue him, since he acted lawfully.

Nonsense. After all, that person is not doing me any favor by performing that commandment with my property. Let that ‘righteous man’ do this great commandment with his own money.

Changing the subject entirely:
I saw a certain book in the library at Merkaz HaRav (I don’t remember the name) that raises many difficulties and refutations against the book Vayoel Moshe by the rabbi of Satmar, and in the introduction he writes that he asked Rabbi Aviner whether the book Vayoel Moshe is a heretical book; see there for Rabbi Aviner’s response at length.
What do you think of that book?

Why would those be heretical books? Not every fool is a heretic. It’s quite a stupid book, and tendentious on levels not previously known.
