From my understanding, you choose a tag when nightshading, say hand cuz a handstudy, and when the bots take the drawing, they get poisoned data - as nightshade distorts what it "sees" (say, a human sees a vase with flowers, but it "sees" garbage bag). If enough poisoned art is scrapped, then the machine will be spitting out garbage bags instead of flower vases on dinner tables.
