Having worked in compliance engineering I have also reported through the IC3 portal, and spoken with lawyers and analysts who register with FinCEN (which, to be clear, is maybe just a step beyond "My Uncle works at Nintendo...") and I have heard that those reports do get reviewed and often acted on, but yes, you will typically never hear back from them. (FinCEN has its own reporting structure, but we also submitted certain reports through the IC3 portal as well.)
