I wouldn't call it a quick hack, and it is fast enough in its current
application. But it is most certainly not intended for fair use enforcement
and it would indeed scale quite poorly if an attempt was made to use it that
way. The filter applies to page views, not edits, so it acts retroactively
for history views and diffs.
