follow or unfollow more than 1000 twitter follows in a day more than the daily limit of twitter

Hi there, Previously my twitter id was hacked and some body followed so many people. And I still have no idea who did this. But I found a way to unfollow them all at one. First I loaded full list of people my twitter used to follow.

Then on right click and selecting console in my browser I typed this command in console.


This way you can follow/unfollow more than 1400. And You can read about the twitter limitations here

But to start following people again you will have wait for another day, with the same command you can friend them again 🙂 enjoy!
