Or, (crazy, wild, new idea here) we use critical thought to identify them, and downvotes to bury them?

As long as the up/down vote system remains transparent on voat, people will be bale to smell something fishy when they see 20-50% downvote ratio compared to the 2-5% ratio you see anywhere else on voat.

For some reason I don't think censorship would be very popular on Voat.
