An anti-detection browser is a special type that transfers your data to the websites in a modified form. Such browsers send a completely different set of parameters about your device and location to the website (browser version, IP, language and much more). This artificially generated data set is called a browser fingerprint witch we use for alternative account detection (Anti-Alt).\

With this feature you can detect and block anti-detect browsers.
