Ivanovich is a common middle name. And in russian language, when you want to refer to someone in a formal way, you use "Firstname Middlename" (unlike "Mr Lastname" in english). That's how you would refer to your school teacher, to your boss, to an acquaintance/someone you dont know closely, how a bank teller would talk to you, etc.

So, no, I doubt they doxxed him.

You joke, but that's pretty much how it is in Russian lol.

Unlike in English-centered naming conventions (and probably others, but I am not knowledgeable enough to comment on that), in Russian you dont really choose a child's middle name. It is always just father's name with slight suffix changes based on whether the person is a male (resulting in a -vich ending) or female (-vna ending).

For example, if your first name is Alexey, and you have a son and a daughter, their middle names will be Alexeyevich and Alexeyevna respectively.
