It's not a huge deal as I don't often include links, but yesterday one of my comments didn't get posted because (I assume) it included a link to an image hosted on Reddit. The image was not offensive in any way, so I imagine there's a policy maybe against Reddit links in general? Anyway, since it takes time for pending comments to clear, I'd much rather know what kinds of links are acceptable in PCG comments to begin with. Who can clarify?
