Microsoft chatbot Tay made a bizarre, short-lived return to the Internet on Wednesday, tweeting a stream of mostly incoherent messages at machine gun pace before disappearing.

“You are too fast, please take a rest,” the teen chat bot repeated again and again on Twitter.

Last week, Microsoft was forced to take the AI bot offline after if tweeted things like “Hitler was right I hate the jews.” The company apologized and said Tay would remain offline until it could “better anticipate malicious intent.”

It’s a problem that doesn’t appear to have been fixed. Interspersed in the stream of “rest” messages on Wednesday was a tweet from the bot that read: “kush! [ i’m smoking kush infront the police ],” a reference to drug use.

Less than an hour after Tay resumed tweeting, the account was changed to “protected” and the tweets were deleted.

Microsoft did not specifically respond to a question about the kush tweet, but did acknowledge Tay’s brief period of activity.

“Tay remains offline while we make adjustments,” a spokesperson said. “As part of testing, she was inadvertently activated on Twitter for a brief period of time.”
