Guys, it's been here for weeks now. We try to zap it as soon as we see it, so you have generally been able to use FP without issue, as we are vigilantly "on the case," as it were. But there have been so many attacks, and there are only so many mods, so sometimes they slip through (usually when we're trying to sleep!). Admin is working on solutions, but you can help by reporting any nasty posts you see.
Sorry for the inconvenience, hopefully it won't be too long now...
