i need it really badly. It's about the one-click porn site in Japan. They will just have a popup window that says by clicking okay you agree to be a member, etc, and they charage like 80000 en or so for the membership fee.

I didn't see the popup box and just clicked okay, so please someone, please translate this page for me!

Don't worry basically, especially you don't live in Japan.
It is set by disregarding in most cases.
I don't translate whole of the page, so I am not good at English very well.
The page says, roughly:
-- List of one-click swindle site
-- What is the one-click swindle ?
-- What you have to do
-- FAQ
-- List of safty porn site

What you have to do:
Case 1: Just you were registered by clicking.

• Disregard it.

Case 2: You were registered by clicking URL on a spam mail.

• Disregard it. Just a charge bill may be sent with e-mail.
• Move e-mail address, if necessary.

Case 3: You were registered by clicking URL on short mail within cellular phone.

• You may have claim calls, but disregard them.

Case 4: You received charge bills by mail, not e-mail, or had claim calls
by phone at your home.

• Ask police office, because they already know your address and/or phone number.

Case 5: Some one came your home or office to collect the charge.

• Ask police office!

Case 6: You were sued.

• Don't worry, you will win absolutely.

I guess your case is case 1 which IP-address and/or remote host are registered.
Excuse me, if the translation has any mistake.

thank you so much for translating it to me!

you have no idea how grateful i am. thank you.
