Whenever I used them (recently) it was because I'd asked a slightly-legal question in some other 'any questions' sub and the mod removed it because legaladvice would help better.

Question literally sat there for 3 days before being answered by someone who didn't have an answer and that was the end of it. Oh wait no it also got a anecdotal story from someone actually somewhat helpful but it was immediately removed by a mod for being too human.

To quote ace ventura, well you did all you could, thanks for nothing.

This is before I realized its actually a sub to catch and neuter any advice that doesn't play into the system's hands.
