It&#x27;s just the &quot;Post hoc ergo propter hoc&quot; fallacy. (Possibly also overactive pattern recognition; how many spams does he get about art at times unrelated to gallery visits?) Google does not sell such personal information to spammers (or anyone else).<p>If you visit non-Google websites, it&#x27;s technically possible for people to discover relationships and target e-mails (e.g. if you entered your email address on website A and then visited website B, cookies can correlate the visits and, among other things, trigger e-mail; also malware and other privacy leakages), but Google does not use its information in the way alleged.<p>Disclaimer: I work for Google in privacy engineering, but I&#x27;m only speaking for myself based on information Google releases: <a href="https:&#x2F;&#x2F;privacy.google.com&#x2F;#google-information" rel="nofollow">https:&#x2F;&#x2F;privacy.google.com&#x2F;#google-information</a>.
