Scammers on the site

We need a button to report users. This is the 2nd time in two months something like this has happened to me:
A person contacts me about a design/job or porject, I get in touch and is someone trying to scam me, aunt dying, rich african woman needs a heir, etc.

Im attaching pics of the last one that happened to me:
