Comment (by SergeyBiryukov):

 Replying to [comment:3 zodiac1978]:
 > The description of the filter is: "Filters a comment’s data *before* it
 is sanitized" (emphasize mine). if we move the filter before the
 `wp_filter_comment()` call it would be already sanitized.

 I think I interpreted `wp_filter_comment()` as sanitization, as its
 description is "Filters and sanitizes comment data", and there are some
 filters in `default-filters.php` attached to its hooks. But yeah, there is
 also some other sanitization code.

 It seems like at least `comment_author_IP` and `comment_agent` could be
 set before `preprocess_comment`.
