Yes the mods over there are that great combination of slow to reply/act on anything, but come down hard when they do. A bit like the person you probably all work with that does nothing all day and then tries to blame it on somebody else when everything falls apart.
For such a big/popular site, they really need to tighten up. I've sent countless messages to the mods on there over the years that have either taken days/weeks to get a response, or have been ignored completely. If you're too busy to be a moderator, don't offer to do it!
