A Request to all those who are trading contents and products on our services

Currently, many transactions are taking place on BOOTH, pixivFANBOX and pixiv Request function.
Among them, we have confirmed that some transactions have violated Article 14, Item 26 of our Terms of Service Prohibited Activities, which stipulates "the act of using this service to display, sell, purchase, register, or otherwise conduct transactions for the following products.

In addition, the terms and conditions of international card brands, etc. also prohibit transactions of content or products that include the following

Child pornography or child abuse
Incest
Bestiality
Rape (sexual acts without consent)
Illegal mutilation of the person or body　
and other acts that are offensive to public order and morals.


We ask all users to check the BOOTH, pixivFANBOX, and pixivRequest functions for the terms of service and whether any of the above items are being handled, and to take action to withdraw or close the items to the public.


■The Terms of Service will be revised on December 15, 2022.

Article 14.26, "Using the Service to exhibit, sell, purchase, register, or otherwise transact the following products" will be revised to make it easier to understand the criteria for products and content that are prohibited from being transacted.

The new Terms of Use will be published in a notice in late November and become effective on December 15 (Thu.).

Please refer to the new terms of use to be released in late November if you are unsure of your decision.
If there are items that are prohibited from being traded on BOOTH, pixivFANBOX, or pixivRequest, please withdraw them or make them private by Thursday, December 15, when the terms will be revised.

If management discovers prohibited items after December 15 (Thu.), the items will be made private.
In addition, if you are continuously trading prohibited items after receiving the measures, we will suspend your account.

At Pixiv, it is our important policy to protect free creation and respect its content.
We believe that creating a safe environment for our users to conduct business with us will help us to do so, which is why we have made this revision.

We appreciate your understanding and cooperation.
