Honestly, I wouldn’t consider this trolling. It’s a low-effort dismissal here (probably why it’s been flagged to death), but it’s still insightful and accurate. The first time it came up, certainly over twenty years ago and I’m not sure how much more (but you can find the form from at least that far back), it was honest weariness with claims of having solved spam.

If you’re not familiar with these things, the keyword is FUSSP (Final Ultimate Solution to the Spam Problem).
