Random FYI for anyone posting in the last few months who've gotten caught up in the Mod Queue and gone "WTF!?" and would like to know what's going on. If LJ could not change settings without notice I'd be super happy about that.
1) If you've been reported for spam before or have been banned from another comm at some point in time in the past, and you are making a post here that includes an external link, your post gets automatically thrown in the mod queue. I approve you, add you to the safe list, and your problem is solved. I'm just assuming you're problem is years old and you're going to play nicely in the sandbox. This cropped up sometime late Aug / early Sept.
2) Sometime in the last two or three weeks LJ added a "URL white list" and defaulted the comm setting to it. Yay, thanks LJ u.u. Basically if you were posting a link to something not on the "white list" you went into mod queue. Pixiv wasn't on it, AO3 wasn't on it, lots of things weren't on it and I really don't feel like maintaining a URL database ~ that's now disabled. Just make sure you post nice links and mark them accordingly.
So unless you fall into category 1, all is back to normal. And if you do fall into category 1, I don't care, its what you do here that counts!
ENJOY THE FRIDAY
