Is there a system that penalizes creators who have fake followers?

Not a single universal penalty system but fake followers carry real consequences, since platforms periodically purge bots and throttle the reach of padded accounts.

Vetting tools effectively penalize fakes by scoring authenticity and surfacing the padding, so brands screen those creators out, which costs them in lost deals.

The real penalty is market-driven, so the most reliable system is you choosing not to pay for fake followers, since detection plus a brand walking away is the consequence that actually bites.

There is no single universal system that formally penalises creators for fake followers, no central authority that fines or bans them across platforms and it is honest to say so plainly. But that does not mean fake followers are consequence-free, because the consequences are real and distributed across the ecosystem rather than handed down by one referee. The social platforms themselves periodically detect and purge bot and fake accounts, which means a creator who padded their following can watch their count drop suddenly in a purge and platforms also throttle the reach of accounts with low genuine engagement, so fake followers quietly suppress the very reach they were bought to fake. So the platforms impose a passive penalty even without a formal fake-follower court.

The more direct penalty comes from the vetting layer and this is the one that actually bites. Discovery and vetting tools effectively penalise fake followers by scoring audience authenticity and surfacing the padding, so any brand that vets before spending screens those creators out, which costs them real money in lost deals. That is the consequence creators care about most, because a reputation among brands for a fake audience closes doors and dries up income and it scales exactly with how many brands bother to check. The flip side is the uncomfortable truth that the system only works to the extent brands actually vet: a creator with fake followers faces no penalty from a brand that does not check and hires them anyway, which is precisely how fake-follower creators keep getting paid. So the most reliable penalty system is not some external authority, it is brands choosing not to pay for fake audiences, which makes your own authenticity screening the mechanism that gives fake followers a real cost. So there is no single universal penalty but detection, reach-throttling and above all brands walking away add up to genuine consequences and the system works best when you do the vetting that makes a fake audience cost a creator a deal.

The penalty that actually works, brands declining to hire padded creators, depends on vetting, which is what the free fake follower checker and the screening in influencer discovery make easy. Your own authenticity check is the mechanism that turns fake followers into lost deals for the creator. Screen audiences before you spend and you both protect your budget and add to the market pressure that makes faking followers genuinely cost something.
