Do you realize that the hosting service you're using (HostGator) is so 
mis-configured that it is exposing your source code and credentials to 
the entire world?

When I go to that URL, I get a page which includes the name of the CGI 
script you are running (/home/nikos/public_html/cgi-bin/counter.py).  I 
can then do a GET on http://superhost.gr/~nikos/cgi-bin/counter.py, and 
can see your script source code, including the credentials to attach to 
your database:

conn = MySQLdb.connect( db = 'nikos_tech', host = 'localhost', user = 
'nikos_nikos', passwd = <elided>)

How to properly configure a web server is way beyond the scope of this 
mailing list, but you really need to do some research there to safeguard 
your own data.
