No worries at all. I don't think the HN thread from three weeks ago made it to the front page (I happened to see it while browsing on /newest). I figured someone would notice and ask about this, so I'm happy to have the chance to explain.
I'm sorry to reach out to you directly on a public forum like this, but my company's website encountered a major negative SEO attack last month and we were hit with a manual penalty by Google today. I thought you might be interested to hear about what happened, and I of course I would like to resolve it as I do my best to always keep my company's SEO efforts within Google's guidelines. Please reach out via email to me at mbrody@myclean.com if we can help each other fix this! Thanks again for everything you do to help make the web a better place, and in advance I understand if you're too busy to respond.
Best regards,
Mike B.
