It's the same thing the Match Group does with their dating apps. They leave the bots up to drive traffic, and keep real users engaged. Then they clear out the bots after letting them run for a bit. You see 20 matches, likes, etc. The moment you pull out your credit card, to "see" your matches you'll find most of them are from bots/ deleted accounts. It's against Twitter's profit motives to clamp down on bots in any meaningful way. Ultimately, these bots do simulate traffic, and when you get your endorphin rush from getting your bot retweets, Wells Fargo or whoever else is advertising on, Twitter gets to monetize you.
