There are a couple of users who email us regularly when they see things like that. This is one of the highest-leverage contributions anybody can make to HN, so we'd certainly appreciate hearing from more such users. Actually I only found out about this subthread because of such an email.
Supercilious complaints, on the other hand, just make the thread even worse. Please don't do that. The thing where some HN commenters use HN to posture over the rest of HN is tedious, and in poor taste. Let's just work together to make it better, to the extent possible.
The stupid game would be making your article title not an immediately obvious summary of your article.
The stupid prize would be this HN thread now that is only discussing the title, instead of the actual article.
EDIT: more specifically .. it's rather ironic how judgmental (and honestly: pretty darn pretentiously) so many here instantly get, yet how there is this implied assumption that the collective wisdom and judgement of this community is above criticism itself, somehow. It might say far more about HN, that nobody appears to be discussing the article's content itself, than it says about the (mis)use of alphabets.
I can read Cyrillic fluently, and a bit of Greek too, yet I'm not in the least bit upset about this pun. If this does upset anyone, maybe it's time for some seriously self-reflection for those people, about what they decide to get upset about and what not.
Thus, the stupid game led to a stupid prize, where major thread (in fact, one that felt like drowning any other discussion) was about the title technicalities, but not about content.
I think it's fair to point out when a good article makes itself inaccessible due to a trivially correctable problem.
I'm not even saying that the author can't make the joke they're trying to make, but even a small title change like "αcτµαlly pδrταblε εxεcµταblε (actually portable executable)" would basically solve the entire problem without sacrificing any of the meaning behind what the author wants to convey with their misuse of Unicode.
It is a good article, which is why the pointless pushback over accessibility is so frustrating. There would be no engineering effort or large compromise required to make the title of the submission readable. It wouldn't suddenly make the article bad, or not worth reading. It feels like it's being exclusionary just for the sake of being exclusionary.
