Comment (by o44czp8oqy):

 In the XML-RPC file, specifically within the pingback_ping() function
 around line 1967, there's a supposed check intended to prevent duplicate
 pingbacks from the same originating server for the same article. While
 this seems like a sensible precaution, upon closer inspection, it appears
 that the check is not effectively utilized. There's an if (1==1) condition
 in place, essentially ensuring that the pingback insertion code is always
 executed regardless of any prior pingbacks.

 This design flaw impedes the ability to call pingback_ping() more than
 once for the same article. In scenarios where it's necessary to parse a
 post body multiple times to detect additional URIs for pinging, this
 limitation becomes problematic. Ideally, we should be able to call
 pingback_ping() multiple times for the same article to accommodate such
 situations.

 To rectify this issue, it's imperative to revise the logic within
 pingback_ping() to properly utilize the intended check for prior
 pingbacks. By doing so, we can ensure that the function can be invoked
 multiple times for the same article, enabling the parsing of post bodies
 as needed to capture additional URIs for pingback purposes.
