Looks like just 2 accounts with 11 total submissions in the last year, both with disclosures in the comments and/or profile https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que....

This post is a bit lighter on that disclosure than I'd like (and isn't as obvious as a Show HN would be) but I feel I missing some big portion of the backstory to this comment?
