Hallo, Platonides,

Are they passing the captcha to create the
account?
Seems so. I've just looked into the source code of the page: it's simple
to find the captcha question and to calculate the answer.
Maybe I have to choose between several spammer blockers which all are
nasty for the good guys.
From the url you provided, I see you are using the math captcha. That
is very simple. You should switch to FancyCaptcha.
