Comment (by swissspidy):

 Hey there, thanks for your report!

 What kind of arguments are you passing to `wp_remote_get()`? Some sample
 code to look at would help greatly.

 Looking at the code from 4.5 and 4.6, no referer was ever set by WordPress
 in 4.5. Now with 4.6, Requests seems to set the referer to the URL being
 requested:

 {{{#!php
 curl_setopt($this->handle, CURLOPT_URL, $url);
 curl_setopt($this->handle, CURLOPT_REFERER, $url);
 }}}

 Citing RFC 2616:

 > The Referer[sic] request-header field allows the client to specify, for
 the server's benefit, the address (URI) of the resource from which the
 Request-URI was obtained

 Seems legit in that case.
