That is a picture of Susan Moskwa, a Google Webmaster Trends Analyst, who works with the search quality team at Google.
Someone sent her an email requesting a link exchange. In fact, it is fairly common for Googlers, including top well-known Googlers like Matt Cutts, to receive link exchange requests via email.
Susan posted on Google+ the email she received and the response she sent back. Her response was, you and your site violated Google's guidelines and will be reported as such.
Link exchange email request:
Hi, my name is Mary. I came across your website, THEDAME.NET, and would like to propose a link exchange between your sites and [redacted].com. Did you know, exchanging links will generate more traffic to both of our sites. Best of all it's FREE; there is no cost or hidden fee. We simply ask for a link back from a page on your site. Simple enough, don't you think?
Here is Susan's response:
Seriously, Mary? You sent a link exchange request to a member of the Google search team, for a domain that isn't even hosted?? You didn't even look at the site, did you. MAJOR LINKSPAM FAIL. I'm reporting your site to Google for violating our Webmaster Guidelines.
Serious response!
