 * I’m not sure where to put this but within the past couple of point releases, 
   something has changed in the comment handling. I see there have been some minor
   changes to the base code in /wp-includes/comment.php but I don’t see how it’s
   created the condition I am experiencing.
 * I have a custom function that’s been running for several years without issue 
   that hooks into the preprocess_comment filter hook to read the comment_author_email
   value in $commentdata. The function had filtered and set the $commentdata[‘user_id’]
   value and passed is back for processing by wp_new_comment(). The custom function
   runs after Akismet first handles the comment and is still functioning properly.
   However, something is butting in and resetting $commentdata[‘user_id’] to 0 before
   it gets to wp_insert_comment(). The only thing I could figure was something was
   hooking into the filters in wp_filter_comment() but it could only be Akismet.
   Akismet has become so complicated that I can’t tell if it’s actually manipulating
   other key=>value pairs $commentdata. I don’t have any other plugins that handle
   comments.
 * Anyway, I fixed the behavior by having the custom function set both $commentdata[‘
   user_id’] AND the seemingly deprecated $commentdata[‘user_ID’] with the same 
   value.
 * The core code has several ternary operators that deal with the backwards compatibility
   to handle $commentdata[‘user_ID’] in several functions, including wp_new_comment()
   and wp_insert_comment().
 * Anyway, I thought I would post this in case someone experiences similar variances
   in comment handling.

 * Can’t be Akismet doing it. I can’t find any code in it to modify the comment 
   in that manner.
 * Akismet actually only works with `user_ID`, but all it does with that is to get
   the user role info for that user ID to pass to the servers for processing.
