This from one of our blackmail forms:

 

She’s already mentioned on your website. Maybe I should have not, but I sent her this link

5 minutes after the end of te conversation, she changed her face book profile.

 

Tell a scammer they’re reported and of course they’re going to change the details.  Now, when they contact someone else, it’ll be with details that aren’t publicly available.  That means no way to warn people about the scammer and more people at risk.  It also messes with any law enforcement investigations into the scammer.  All because the person just HAD to tell the scammer they were reported!
