How odd. This is a rather interesting catch, especially in light of the upcoming tax fight in 2025 with the TCJA and Expanded Child Tax Credit expirations, and the unrealized capitals gains tax proposals.
Given the other comments pointing to the SEO benefits of creating a subreddit just for a single post, it has shades of an effort to seed the information space and shape the narrative in advance of the tax fight by gaming the search results prior to uninformed journalists and legislative aids developing an interest in the topic, many of whom will search Google for background information and context as the tax fight plays out.
Nice catch, and interesting regardless of the motives.
