Human In the Loop Test
The senders of unsollicited mail aka SPAM more and more use automated engines to
collect e-mail addresses of future victims and to sign up with free e-mail services to
send their unwanted messages. "Human In the Loop Tests" are a technique that makes it
significantly harder for such engines to so by requiring to copy a text that is
easily recognizable for the human eye, but hard to decypher for automated engines
because this text is not constructed out of normal computer characters, but in fact,
is an image in single dots. Just copy the displayed character sequence into the field
next to it. Doing this will reduce the incidence of SPAM to an easily tolerable level
