Hides scripts for popular browser games and social networks as well as scripts that use "foreign" characters in descriptions, when browsing or searching scripts.
i.e. it filters any/all of these 4 categories:
Games: scripts for browser games like Kingdoms of Camelot, Mafia Wars and Ikariam
Social Networks: scripts for general purpose social networking sites like Facebook, studiVZ and VKontakte
Non-ASCII: scripts that use non-English characters in description (accents, umlauts, cyrillic letters, ...)
Clutter: obvious spam, titles like "asdasdasd", description = title, title < 6 characters, "just a test", scripts for themes/dark/night mode (because they are, in effect, userstyles).
The filters list appears just below the #script-list-option-groups element (i.e. on the right).
Note: you may modify the value of line const DEBUGGING = 0 to 1, in order the filtered scripts to be highlighted yellow -instead of hiding them- so that you can check which scripts have been filtered.
