Poker is an (almost) unique site in the Stack Exchange network, in the sense that it has only two (pro-tempore) ♦ moderators. Three is the standard for beta sites. As mentioned here, one of the initially appointed moderators is no longer active, so only two remain.
That doesn't need to be a problem per sé, but the symptoms (IMHO) are. Case in point are spam posts. You can look here to get a feeling for what kind of spam is being posted here; mostly (very) low quality posts with a link to the online poker site of the week. Our bot, Smoke Detector catches a reasonable portion of those, but there are not always six people around to nuke the post (some of our members don't even have an account here). These two posts have been on the site for three days (with some spam flags, but not enough to destroy them). I'm not sure if this is because it's holiday season, but I expect at least one mod to check up on the site every 24 hours, even on a small site like this one. We've seen more long-living spam on Poker Stack Exchange in the past, so I think this is not just an isolated incident.
Of course, appointing a third ♦ moderator is not guaranteed to solve this problem, but at the very least, it will help.
