In an article posted today, Alastair Rampell tells Tech News World:
If you’re upset that your friend sent you an e- mail using DidTheyReadIt, then that’s a problem between you and your friend.
If he really thought that, why does DidTheyReadIt have to use a web bug? In most cases, I do not think people are even going to know that someone has used the service.
I know that someone loaded the web bug in the message I sent to his email address (email@example.com), and apparently had it open for over four minutes from something in California. I have not received a reply yet, but I know the message got there.
And, not only that, I posted one of their web bug URLs (http://didtheyreadit.com/index.php/worker?code=844eea38c4f0ab9bd2220f65f4107dbe) in my use.perl journal and it has been picked up by a couple of spiders. I am not sure why spiders are loading images, but I guess some do.
