Nikita publicly talked about wanting to go even further to kill those spammy foreign reposter accounts but X eventually pulled back at some point. Lots of the big X accounts complained and they came to some half-way middle ground where they released the country-of-origin feature + a more limited demonetization campaign. Which is still admittedly better than most social media companies have done about the issue. I guess those low quality reposters are just too popular among the public (Youtube shorts is notorious for this).
