I presume they are either still investigating what they know and/or may have not received a well-detailed lead. As a more investigative scambaiter with a Bachelor’s of Science in Journalism, I work to try and generate as detailed a lead as possible by gathering as much data about the culprits as possible whilst properly citing my sources with appropriate screenshots and hyperlinks.
This also holds true for my recent thread on Cadre Informatics based on a lead I got from @richardharis. I simply published what I knew, with appropriate sources, and relayed the information to the FTC, Office of the Inspector General and the Texas Attorney General’s office.
