Free bots use outdated API endpoints. When you "like" a post via a cracked script, Facebook records the action but does not display it to others. You see the like; no one else does. It is digital masturbation—zero social proof.
If you own a Facebook (not a personal profile), you can use ManyChat or MobileMonkey (both have free plans up to 1,000 contacts). These tools auto-respond with likes and reactions based on keyword triggers. phantombuster facebook auto liker free
