Yes, Twitter allows only a limited number of accounts. If it detects multiple logins to different accounts from the same IP, it may block them all without the possibility of appeal. However, you can use a browser that supports multiple accounts and also has anti-detection features. In other words, each of your accounts will log in using a different IP address, so your accounts will not raise any suspicions with Twitter.
