Nintendo has announced it will suspend the 3DS's Swapnote application due to the distribution of offensive material.
The service, which allows users to exchange hand drawn messages using either Spotpass or Streetpass, will no longer be available from October 31.
"Nintendo has learned that some consumers, including minors, have been exchanging their friend codes on Internet bulletin boards and then using Swapnote (known as Nintendo Letter Box in other regions) to exchange offensive material," the company wrote on its website.
"Nintendo always wants to provide a positive experience for all consumers and limit the risk of any inappropriate activity or misuse of a service. We feel it is important on this occasion to take this action."
Swapnote released to Western consumers in January 2012 as a free application accessible through the Nintendo eShop. The ability to exchange photos was introduced in April.
This follows news this week that the 3DS has sold less in the first half of 2013 than it did during the same period last year.
Nintendo made $2 million in sales in the six months since April and made a net profit of $6.1 million.
