It is the primary mode of Russian paid trolls to use the "tu quoque" method of argumentation ("You do it too!") in online discussions. However, tu quoque is a fallacy. It is irrelevant to the discussion if other places do other things. We are talking about this specific instance. It also is trying to create a false equivalence, stating that if a bad thing happens once in country A, it is as bad as country B. However the frequency and severity of these matters is almost universally different, which shows the false equivalence.
