Thank you for adding your perspective, I think I understand your point (by nothing to sneeze at I took as meaning not a big deal) but it's more a matter of principle. Am I being blocked for asking someone to focus on the article's issues or for saying that person has a COI? I don't mean to sound indignant but either way there are other ways of handling things, but at least I should know what the deal is.

I mean the blocking admin accused me of making ad hominem attacks, which I have most certainly not (especually if one goes by the definition in the wikilink: An ad hominem argument, consists of replying to an argument or factual claim by attacking or appealing to a characteristic or belief of the person making the argument or claim, It'd be nice to know what exactly this admin saw as one.
