RedFlag is a Chrome extension developed by kathleenburk08 that aims to address the issue of cyberbullying on Twitter. This free program offers users the option to hide or highlight social media posts that might be considered harassment.

Once installed, RedFlag will load whenever you are on Twitter. Depending on the settings you choose, potentially harassing tweets will either be hidden or highlighted. If a tweet is flagged as potentially harassing, you will be directed to the developer's help page for further information and guidance.

The detection of harassment is done through a two-step process. Firstly, the extension uses sentiment analysis to determine if a tweet has a negative sentiment. Secondly, it scans the tweet for profanity, threats, and user mentions. If a threat is detected, the tweet is automatically flagged as harassment. If there are no threats, the presence of profanity, the sentiment of the tweet, and any user mentions are taken into account to determine if the tweet is considered harassment.

RedFlag can be downloaded from the Chrome Web Store, providing an accessible solution for users concerned about potential cyberbullying on Twitter.
