I think that KYC\* is important for preventing crime, scams, and **identity theft:**

Never trust unauthenticated claims of identity. Always _demand_ and _verify_ digital signatures.

The same page has links to some archives and mailing list posts, showing some evidence that I have had the same PGP key fingerprint since, at the latest, December of 2017. It is not cryptographic evidence; you must exercise sound judgment about how difficult it would be to fake. More could be found by digging around. I created the key in March of 2017; but IIRC, the only place I could now cite as evidence earlier than November or December was a defunct Keybase account.
It is important to make sure that you have the right key. For an object lesson to newbies, I trivially created a fake key for Satoshi Nakamoto:

**Verify the signed statement. Verify it yourself! Don’t claim to others that you verified it. Don’t rely on others’ claims to have verified it. And don’t do this** ([xkcd 1181](https://xkcd.com/1181/)):
How? There are plenty of PGP guides out there on the Web. For instance, I am credited in [the Bitcoin Forum’s Indonesian-language guide to PGP](https://bitcointalk.org/index.php?topic=3221263.0), by a Bitcoiner whom I helped to learn PGP in early 2018. (He later translated my above-linked Anastasia essay and my [Bitcoin Social Phenomenon](https://bitcointalk.org/index.php?topic=5215927.0) essay to Indonesian; thanks, PGP!) For other guides, try your favourite non-Google search engine.
Well, now you know how _I_ do KYC. Only one more KYC verification is needed…

I had intended to make this post upon my return to this forum. Alas, my alleged robotic AI is returning `ENOTIME` errors behind an ever-deepening pipeline of posts that I need to finish writing. (Will do elsewhere later.) This is belated, but important.
Password authentication is weak. [Data breaches are rampant](https://haveibeenpwned.com/), sometimes with [nasty results](https://www.troyhunt.com/heres-how-im-going-to-handle-ashley/). Even if _my_ passwords are strong, this forum is a centralized service not under my control; it could have been compromised.
When a cypherpunk’s forum account awakens after years-long sleep, it is wise to check ID—the cypherpunk way. And I want to set a good example here: People need to learn to do _crypto_. **If you don’t do PGP, you don’t do crypto.**
Extra ~~merits~~ “likes” if someone could please explain [the proofs that I designed in my Nullian Verification thread](https://bitcointalk.org/index.php?topic=5233083.0)—and especially if someone here credibly demands such a proof from me now. “Credibly” in the sense of, “sincerely interested in verifying it—not wasting my time”. I sadly gave up on what I was doing with timestamps: Insofar as I could tell, _nobody_ was verifying the proofs. (Pun intended.)

I like that you raise some relevant issues but harassment is against the CoC in whatever form it takes and the tenacity exhibited in some of your posts are more than borderline.
