Actually, our tool includes a blacklist and various security methods to prevent shortening potentially harmful links, such as those used for spam or phishing. While this feature is designed to protect users, it can sometimes block legitimate URLs that contain keywords similar to those found in malicious links. If you are confident that your link is safe, you can contact the developer for clarification to allow an override or whitelist for your trusted domain.
You shouldn't rate before fully understanding how the tool works. It's too harsh and may not reflect the tool's potential.
