This video delves into common account suspension and registration failure issues in Facebook multi-account management, revealing the root causes: IP address pollution and browser fingerprint association. The video points out that simply clearing cookies or using incognito mode is far from sufficient, as Facebook identifies account associations through multiple dimensions such as device type, browser version, time zone, language settings, and even Canvas fingerprinting. The author demonstrates in detail how to use MasLogin anti-detection browser to create completely isolated browser environments, including independent cookies, storage, time zones, and system fonts, with each profile possessing a separate and clean digital identity. The video also showcases the effects of using multiple profiles with different IP addresses, datasets, languages, and time zones through actual tests, with all security detection results showing 100% safety. Finally, the author shares practical tips for account maintenance, emphasizing that newly registered accounts should not have their information modified immediately but should first undergo an 'account nurturing' process, helping users completely bid farewell to the troubles of random suspensions, abnormal verifications, and wasted accounts.
