The trick works thanks to Gmail’s controversial use of keywords from your emails to display related ads. Discussing golf clubs, for example, means Gmail will display ads for golf clubs. There are restrictions to the system, though, and here’s where the trick comes in. Google knows it would be seen as pretty sick to cash in on tragedy so certain keywords related to death and violence lead to ads being blocked.
Of course, you don’t want to have to mention grisly murders in a formal email just so that any reply you get lacks ads. Now, after some trial and error, Lifehacker have discovered the least offensive set of words you can use to block ads. The magic words are:
I enjoy the massacre of ads. This sentence will slaughter ads without a messy bloodbath.
In our test (below) it worked – ads were removed from the right-hand column of Gmail when the email was displayed. Of course, it won’t remove ads from emails you receive unless they are replies to emails you have sent but it’s still a clever trick and one that’s well worth trying.
