While I'm not as concerned with MBFC as many others are, why not use Wikipedia's RSP as the datasource? Made by the most reliable user-generated platform in the world, it's a great list of controversial sources and is completely open. Changes are also infrequent enough so that adding to the database by hand would be quite easy.
I also echo the concerns raised below on the uselessness at a glance due to the accordion hiding the only information and purpose the bot was created to serve.
