Previously, previously, previously, previously.
Off topic: The title of this post in "Recent Posts" is some other random number on other pages. Is your blogbeast confused by it's title?
E.g. it's 13252130 on https://www.jwz.org/blog/tag/big-brother/
and it's 13252124 on https://www.jwz.org/blog/tag/conspiracies/
They are both 13252140 for me.
On the main page, both of the above comments are stated in the page text of the Recent Comments section for me as 13252157, although the link address is to 13252140.
When I clicked through to this page, the text in the Recent Comments list for both comments shows as 13252140.
I see 13249664 from a totally unrelated page, and 13252140 on this page.
The actual URL for the entry "13249664" from that page has 13252140 in it, which explains why it "works". But overall I think this is just more of the WordPress/ MySQL/ PHP garbage fire and we should ignore it and hope it goes away.
While writing this I opened another unrelated page and that uses 13246495 to name this entry but again has correct URLs.
