It does exist. You just have to use your eyes and the search feature to find it, which again, has already been proven.
Math time!
Lets just assume that all 10 pages of post with
the word pony in it are MLP related (and that's a really generous assumption)
Last month there were 138131 / 15 = ~9,200 pages of posts.
10 / 9,200 * 10 = 0.0108%
so just a 100th of a percent of post last month have been pony related, and the way I did m calculations were extremely in you favor.
1/100% of pages of post isn't really a problem
