By publicly posting on a post you are inviting anyone to comment and give input, regardless of your friendship with CD the comment was in no way needed and can be take in bad taste, to avoid such repercussions next time, try to consider the environment you are in and the context of your postings.
CD is my friend too, and you commenting what you did led a lot of people, not just myself to think you were trying to harass him. or troll that thread it being outdated and all. This is a public forum and your actions should reflect such.
It's all about perception, young one. Posting something in a public domain leaves of open to interpretation by all. This includes members of the community tasked with upholding it's standards. If they decided to let your case slide without any intervention, think of how the rest of the community may perceive this act of leniency; a potential bias. Consider your audience before submitting messages.
