Honestly - and this is not based on any concrete evidence or any secret inside-knowledge - I feel like this is NOT due to a government agency. The gov't would much rather make big busts and big headlines about taking down SR and its vendors / buyers. They wouldn't do it quietly, and they wouldn't do it by simply causing users to migrate to another marketplace. They want results, and for them, that means busts. In my opinion, this is much more likely to be due to a rival marketplace or people trying to blackmail DPR or something like that. Something non-government-related.
