Finally, the untrue claims in this blog post are being plastered all over rBTC but due to actions by that subreddit's moderators I am unable to post a counterargument-- not just on rbtc-- but anywhere on Reddit. Yet they happily scream about far less limiting actions a censorship.
Then why don't you post it directly on the blog? What a better place to show to everyone that he is wrong?
You can archive it if you are afraid of a possible censorship from him, and show it then to everyone.
