This submitter under other usernames sova and cushpush, have been promoting their japanesecomplete site since 2019 (https://news.ycombinator.com/from?site=japanesecomplete.com) and miso site since 2023 (https://news.ycombinator.com/from?site=miso.beehiiv.com) against the HN guidelines on self-promotion. Turning on "showdead" reveals more of the history for those interested.

Also, there are four previous postings under the sova account, so this is not exactly new. Show HN is not for advertising products.
