Interestingly enough, Wikipedia’s sourcing list counts Wikipedia as unreliable. It says you need to find information somewhere else so as not to create a self-referential loop. You have to justify it from a solid source that’s outside the system.

MBFC says that MBFC is incredibly reliable, and incidentally also tends to mark sources down if their biases don’t agree with MBFC’s existing biases, which are significant. It needs no outside sources, because it’s already reliable.

Good stuff.
