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.
John Mueller from Google said that he gets between 3-4 a week of these a week.
