Proof that I can still sign with my key:
-----BEGIN PGP SIGNED MESSAGE-----

My below modification of subkeys/userids proves that I still control the certification-only primary key. I have mentioned before somewhere, the primary key is exclusively kept on an airgap machine. (man gpg, look for --export-secret-subkeys)
I dislike distributing my key this way, especially since I intend to soon do more key maintenance. However, with the keyserver network permanently b0rked, this seems to be the best available means for me to distribute to the forum all of my userids (including those with no mail), revocations of userids for mailboxes that no longer exist, and so forth. The most useful parts of the key are on keys.openpgp.org, as linked in my signature.
Here is my refreshed key with some userids revoked, and a new expiration for the encryption subkey:

Despite no PGP key referenced earlier in this thread, a previously signed message in 2017 using the same key is more than enough to verify the user:

The only inaccuracy is that nullius signed proof in 2017 a day later than speicfied
* email address removedNeutral trust left confirming this proof of ownership:
This user is still in control of their account after a period of absence as verified with PGP. Proof has been signed and verified with a 2017 public key that was used to sign a message the same year. Negative trust concerning this "issue" of absence should therefore be completely ignored, due to the concrete cryptographic evidence presented in reference*.
*Trust amended due to negative trust now removed.
