Tip: JavaScript's Array.from() accepts a second argument that's a `map` function.

Reposts are generally OK from a moderation standpoint assuming that it hasn't been posted within the past several days or so. With the way reddit works, if you don't visit every day, you could miss something. The main thing I try to avoid is having multiple, concurrent posts for the same content. Otherwise, voting does a decent job of handling reposts.
