You can use
TweetAttacksPro to do this. You can choose do not bind proxy for your account. Proxy is to make sure the account which is logged in each time is always using the same device and same ip address. So that would decrease the risk of banned by Twitter.
You can go to watch some videos and read document to know how to use it. Also you can download some sample tasks to use directly.
