[BUG] Filter javascript garbage (especially for clickbait detector)

[brogly-zz]

There is a lot of garbage javascript on many pages that ends up being passed into the clickbait detector. This results in essentially just code being classified which throws off overall page results.

Usually, these contain

• "function() {"
• a large number of curly brackets
• var statements

Have not investigated why/where this JS code gets pulled in from thoroughly but it frequently happens and should be prevented.
