Twitter has, for years, recommended accounts for users to follow, and the company's recent push has been to bring those recommendations to the direct message inbox.
Now users can manage the recommendations the company sends their way. Those who follow @MagicRecs, a Twitter-operated account that sends its followers suggestions on who to follow and what tweets to check out, can now respond to the bot through direct messages or replies.

Users can send simple messages like "good" or "bad" to let the account know if the recommendations are relevant. If users want alerts on who to follow but don't want alerts on popular tweets, messages like "users on/off" or "tweets on/off" will alert the bot to change the recommendations it sends.
Now you can send me direct msgs to share feedback or customize your recs! Send "hi" or "help" to start. More info https://t.co/jvs0lAaO2d

The account also responds to messages like "hey" or "hi," and sending a "help" message elicits a response listing all of the actions you can take.
@MagicRecs is one of Twitter's numerous experiments on new features and ideas. Another recent test, @eventparrot, sends its followers breaking news updates to their inbox as well. (Users can turn this off in settings if they don't want recommendations.)

Capitalizing on the the success of @MagicRecs, Twitter implemented a new feature in September that sends users follow and content recommendations via push notification, even if they don't follow the @MagicRecs account.
