Vladimir, are you at liberty to confirm whether you have provided any of my various posts today with negative votes, and how many?

Your challenge here prompted me to downvote each of them myself, after a brief confirmation. The multiple advertisements for your "book" also don't help.

I await your detailed reply to the basic issues I have outlined above in any event, but I read somewhere that it is common for unexplained negativity from others to be explained when asked. What is your explanation, if any?

Downvotes mean "I want to see less comments like this one". Since this currently applies to every one of your comments you may consider contrasting your comments with the ones that are voted highly and seeing if there are any features worth emulating.
