If you've got a powerful GPU in your machine, it may seem like a bit of a waste to leave all the computing power sitting in the background, doing relatively little at idle. In which case,, a company that offers game codes, gift cards, and other items in exchange for users GPU resources, might seem like a reasonable way to put your machine to work.
Earnings created by renting out GPU time to Salad are redeemable in the store front, in which users can trade in their gains for a variety of rewards, including Roblox gift cards, Fortnite DLC skins, and Minecraft vouchers."some workloads may generate images, text or video of a mature nature", and that any adult content generated is wiped from a users system as soon as the workload is completed.
The creation of non-consensual sexual imagery of real-life people strikes as particularly deplorable, and that in combination with the level of abstraction here means that many may well have been generating this content on their own machines with no explicit knowledge of what they were signing up for.
