I have it on many pages of the site. If you click the box
you will see a long list of rubbish email addresses. This
will do no harm to your computer.
Nasty people use 'Spam Bots' to search through web pages
looking for email addresses. These addresses are then used
by spammers to send junk emails, sometimes genuine adverts,
occasionally containing viruses.
The above box provides the 'Bots' with lots of tasty email
addresses - unfortunately (for the spammers) they do not exist.
But their computers fill up with these addresses, which means
they have to spend time removing them. With a bit of luck
they might even stop the spammers for a few hours.
Because my email address used to be visible on the site I
get lots of spam. My new contact address is hidden (see Mailto
Page), time will tell if this has worked.
