Use Text Patterns (Regex) for Filters

Ads Example:

FEEDFLARE_ADS = %r{
     <div[^>]*?
        class=("|')feedflare\1
        [^>]*?>
          .*?
     <\/div>
       }mix

FEEDBURNER_BUGS = %r{
      <img[^>]*?
         src=("|')(:?http:)?//feeds\.feedburner\.com/~r/[^>]+?\1
         .*?>
       }mix

...

or as one-liners (if you prefer)

FEEDFLARE_ADS   = %r{<div[^>]*?class=("|')feedflare\1[^>]*?>.*?<\/div>}mi
FEEDBURNER_BUGS = %r{<img[^>]*?src=("|')(:?http:)?//feeds\.feedburner\.com/~r/[^>]+?\1.*?>}mi
...
