The “clickbaitiness” of HN posts is increasing, and I don’t like it.
The post's title isn't clickbait. It's a wording style that simply has many auxiliary verbs and grammar articles removed.[1]
Anyway, the same sentence with extra helper words in [] may help in parsing it:
"[The company called] Gated [has a junk email filtering service that issues] challenges [to] unknown senders [by forcing them] to donate to charity in order to reach you"*
Debatable, it’s definitely written that way here on HN because not knowing what’s about triggers our curiosity. Is the educated version of “You won’t believe what happened next”.
