We're actually in a process of cleaning up the FAQ by removing old or poor answers, but it's an entirely volunteer effort (as, of course, everything here is -- moderators do not actually get paid in Amazon gift cards per person banned).

The (informal) policy has generally been that we consign poor answers to the dustbin of history and replace them with good answers. Editing old answers at this point would require us to reach out to every individual writer, many of whom have moved on.

All that said, though, we appreciate the question! If you find bad answers in the FAQ, let us know -- either send a modmail or hit the "report" button and we'll take a look at it.

Thanks!
