That is strange, also do a search for something like "pokemon card prices" (without quotes), they're not using exact matches, but in the listings they only highlight "pokemon" if it's used next to "card".
Still DOA. I have found about 100 words like that. Some are pretty common terms. There must have been so much EPJC (evil page jacked cloaking) that they had to just remove the term from the database. I've quietly removed all my 'pokemon' pages.
