I see several comments like this implying nothing can be done. But that is far from the truth. First, an agency that actually answered the phone could coordinate directly with LinkedIn and other tech companies to quickly take down these fake accounts and minimize harm to others. We all know how incredibly hard it is to contact a tech company. Second, an agency that answers the phone could help less technical people find what may have been compromised and push people towards support services if needed. And finally, maybe, they could do the hard job of combining leads and working with appropriate agencies to maybe find and prevent these things over time.
