For about two decades, there has been persistent Ilya confusion. Ilya Somin of George Mason University is often confused with Ilya Shapiro, formerly of the Cato Institute, and now at the Manhattan Institute. They both share the name Ilya, they both are legal scholars, and both share (or at least shared) similar philosophical views.
Longtime readers of JoshBlackman.com will recall that I wrote a series of posts about "Ilya Confusion" starting in 2010. Indeed, that year, I held the "Battle of the Ilyas," a trivia contest to determine who would be the real Ilya. For those keeping score, Ilya Shapiro prevailed.
Even then-Justice Willett tweeted about the Battle of the Ilyas!
