To provide a bit of context, in March 2013 Gregory Maxwell wrote a patch for bitcoin core that censored satoshidice transactions by refusing to relay or mine transactions with outputs less than 10k sats. https://bitcointalk.org/index.php?topic=149668.msg1598216#msg1598216

This patch was explicitly called out as censorship by people in that thread (see the post by OneMiner at the top of that thread) but within a few months bitcoin merged a code change that implemented a less severe form of the same thing, making the dust limit 5400 sats. Satoshi Dice relied on its ability to create utxos below that dust limit as a way to alert users of the service if they lost. But once that change went into place, the number of dust transactions fell drastically.

In other words, censorship works. I'd like to use it once again and "dust" off this reliable old tool from our tool belt.
