Every time I’m given a captcha, which is often since I’m on a VPN, I intentionally get the first few wrong, just to do my part to poison their data.

Hey uhh… Can I get the collection somewhere

Unfortunately I’ve heard the list is not well-enforced, so the do-not-call list functions more as a list of confirmed working numbers with humans on the other end. That’s why I’ve never tried using it…

I get probably 5 spam calls a week so if that keeps growing, I might have to give it a try…

I wouldn’t be surprised if part of this remaining value is because the Japanese internet still heavily relies on it as a platform, even if the west has begun moving elsewhere.
