Some of the tweets people highlighted weren't repeat after me at all. The article mentioned one, but there was a lot like that where Tay seemed to have learned to speak positively about very bad things. Had it been just repeat after me, all Microsoft had to do would be delete the offensive tweets made by Tay and then turn off that feature. There was more going on.
