Top services offer a refill policy. If Facebook removes the likes within 7 days, they add them back for free.
Most top-tier auto likers only ask for the Facebook post URL – not your login credentials. This is a significant safety advantage over older tools that required full account access. You simply copy the link, paste it, select the number of likes (e.g., 100, 500, 1000), and complete a captcha or a simple task.
