I don't think it's realistically possible to do more than you've done unless you have huge resources or swap professions and become a full-time scam-buster (there are a surprising number who make that swap) - that said, I think it's important to carry on doing what you can when you spot these things - it's whack-a-mole for sure but the more who fight back the better, and it gives a bit of support to those who choose to make it their primary goal, and really go to town chasing these people down. Thanks for the article.
