If you do type that, you will be greeted with a bug—a bug that reveals your private messages.
The glitch was discovered by a Reddit user who incorrectly typed in the website URL using the Google search app. However, instead of typing the1975.com, the user added an extra period and searched for ‘the1975..com’ and like you’ve figured, the page ended up displaying the SMS inbox as opposed to the website. Interestingly, iOS users don’t seem to have the same experience.
So, what’s the cause?
Apparently, the syntax is tricking the Google app into thinking that you are issuing a “show my messages” query, and to fix this temporarily, you have to revoke the Google app’s SMS permission.
Now, the result shown by Google Search is not new and is the same text message summary that can be invoked by asking Google to show your text messages. However, it’s a bug and hopefully Google issues a permanent fix, but until then, did you get the same result?
