The e-book site also recommends the authors to rewrite their books so that they can return to the market without containing so-called "LGBTQ propaganda".
"We suggest that authors whose books may contain LGBTQ propaganda change their texts so that their work can be re-released on the market after modifications and subsequent moderation," Yevgeny Selivanov, head of content development for the Litres group, told Russian news agency RBC.
"Will get much worse"
It was almost ten years ago that the Russian law against so-called "LGBTQ propaganda" was hammered through.
The law then meant a ban on directing so-called propaganda, which contains non-traditional sexual relations, to minors.
The new law applies to everyone in the country and covers art, books, films and plays that are considered to contain something that the authorities believe advocates homosexuality.
- The purpose of the new law seems to be to make almost completely invisible the millions of Russians who do not want to live in heterosexual relationships.
They have had it very difficult for a long time and now it is going to be much worse, says Bert Sundström, Russia correspondent at SVT.
