Ideally? A jury of your peers supported by a system that at least purports to provide checks and balances against the system being dominated by any single person or groups' judgement.

If factual veracity faced a similar system that tries to balance the needs and desires of all participants, then censoring misinformation would be a lot more palatable (and would still, like our justice system, often be wrong.) The current system of supressing misinformation has none of the check and balances contained in the legal system and adding those in would do a great deal to facilitate trust in that system.
