Freedom of speech should come with freedom to hear (or not) otherwise it'd just degrade to useless noise drowning out anything of value. Creating garbage speech is typically much easier than something worth hearing so a single asshole can flood the whole board with nonsense. We do have some tools to that effect (Ignore) but unfortunately they don't work when the forum favors 50-account trolls.

Perhaps we should do it the Bitcoin way and charge a TX fee for each post
