Hi John, welcome to HN! Argh, I'm terribly sorry that you were getting rate limited and have turned that off now (I'm a mod here). Our software does that because of past abuses by trolls, and the fact that it also affects users who show up here to discuss their work is the thing I hate most about our entire system.

Please comment as much as you like. I've also unclogged the pipes so that your blocked comments have now all gone through.
