First of all brother, if I may say, your attitude is all wrong.
To understand how to bot something or automate that part of your business, you need to dive deep and learn what it is you're automating.
Automation is very tricky, it's not just as easy as saying, "I'm gonna bot Twitter" and then you turn on a bot and then it happens.
Automation may simplify your life, but automating things takes time and trial and error and refinement.
It's the scientific method in a nutshell.
Let me ask you this. You say you want to run 50-100 accounts, but right now, how many are you currently running?
Do you know the magnitude of damage you can do to a Twitter account if you send 50-100 botted accounts to interact with it without having a clearly defined plan or any idea what you're doing?
It's better to experiment small and scale up. The suggestion given to you by greenbrush is very valid because with the method she shared, you can practice, learn the process and refine your strategy. Then scale what you see works and refine what needs changing.
Good luck brother.
