Just for laughs: try saving the source of the Mudcat home page. Then change that iframe line to

<iframe src=http://www.2345.com/?ktjwh202 width=600 height=800></iframe>

and reload that source into your browser. It will put 2345's input in a window large enough for you to read. You can now save the frame and feed it into Google Translate - it does a very good job.

It doesn't appear to be malicious but it certainly isn't what anybody comes to Mudcat looking for.
