At the IMO "silver medal" afaik is define as some tange of points, which more or less equals some range of problems solved. For me it is fair to say that "silver-medal performance" is IMO langauge for about 4/6 problems solved. And what's the problem if some clickbait websites totally spin the result? They would've done it anyways even with a different title, and I also don't see the harm. Let people be wrong.
