The problem with the title is simply that the English language allows open compound words. I know many Germans wonder why we allow this. Germans push the words together, for clarity. I've suggested that we use hyphens. Hyphens feel natural in English, and could remove the ambiguity that exists whenever we use open compound words (that is, open-compound-words). In this case "not-comments" would have added clarity.
Likewise, the title "World's longest DJ set" was confusing, because most people will assume that the compound word is "DJ-set". But if you read the whole article, then you realize that a python snake fell on the mixing board and accidentally mixed some tunes. So the compound word was actually "longest-DJ" -- a 2.5 meter python.
We should all consider using hyphens for all compound words.
