Why can't I follow people?
If you're unable to follow more accounts, you've probably hit a follow limit. Twitter has imposed reasonable limits to help prevent system strain and to limit abuse. Remember that:
If you hit a technical limit, you'll see an error message when you try to follow.
We do not limit the number of people who can follow you.
Twitter's technical follow limits:
Every account can follow 2,000 users total. Once you’ve followed 2,000 users, there are limits to the number of additional users you can follow. This number is different for each account and is based on your ratio of followers to following; this ratio is not published. Follow limits cannot be lifted by Twitter and everyone is subject to limits, even high profile and API accounts.
Every Twitter account is technically unable to follow more than 1,000 users per day, in addition to the account-based limits above. Please note that this is just a technical limit to prevent egregious abuse from spam accounts.
Accounts are also prohibited from aggressively following other users. Our Follow Limits and Best Practices Page has more information on Twitter’s following rules.
