This post is ten years old, the code was last updated nine years ago. It's likely the site in question has changed substantially in that time.

You are right, that was a stupid remark..

Not stupid at all. Sites and front end interfaces to services change over time, this is one of the reasons that public APIs are available, to provide access to services without automating the user interface. Perhaps this site has such an API. See Babelfish alternative regarding translation services.
