Why the special authentication ? The instructions are there for anyone to get in !
Yes, any human can get in, but what about robots ?
Probably all of us have received annoying e-mail messages, aka spam.
You may ask yourself: How did they get my e-mail address ?
Quite often, e-mail addresses are gathered from web pages by programs
specifically written for that purpose.
The programs are similar to the robots used by good search engines,
such as google.com and yahoo.com.
The bad programs are sometimes called badbots, spambots, and spiderts.
They are bad because they do not obey the robot rules established by web designers.
If the contents are not protected,
a badbot could find the contact page inside,
and potentially gather/harvest the e-mail addresses there.
But I can see the User Name and Password. Can't a badbot see them too ?
You are looking at an image, and not at real text.
From what I have read, badbots do not contain Optical Character Recognition
(OCR) methods.
The bots would then be too slow (in the year 2002).
After I get to the homepage, is it OK to put it in my favorites/bookmarks ?
Yes, that is safe.
If I make a webpage, can I put a link directly to the homepage ?
Yes. that is safe too.
