Besides using fingerprint browsers, you also need to continuously warm up your accounts:
Fill out a real and complete profile, including profile picture, cover photo, bio, education, and work experience. This makes your account look more authentic and reduces the chance of being flagged as a bot.
Stable Login
Try to log in from the same device and IP address consistently. Avoid frequently switching locations or devices to prevent security alerts.
Normal Usage Behavior
Spend some time daily browsing feeds, liking, commenting, and sharing. Mimic the activity level of a regular user. Avoid adding too many friends or posting ads all at once.
Be Cautious When Adding Friends
Limit the number of friend requests sent daily. Prioritize adding people you know or those with similar interests, and avoid mass-adding strangers quickly.
Diversify Your Content
Post original content, share articles and videos, and vary your activity to avoid appearing overly promotional.
Avoid Sensitive Actions
Don’t frequently change your name, profile picture, or contact info. Also, avoid posting content that violates Facebook’s community standards.
Bind Phone Number and Email
Link a real phone number and email to your account for easier recovery and security verification.
Join Groups and Participate
Join Facebook groups related to your interests and actively engage. This increases your account’s authenticity and activity.
