Thought that might be it. I've removed the recent spam and banned the spammers - but let us know if you find more (you can click "Report inappropriate content" under the little three-dot menu on the post). Wild Friday night over here!
Cleaned up again... what a waste of everyone's time. Though, TBH, I'm surprised this kind of thing doesn't happen more often. I'm going to adjust some of our spam-prevention settings to make it a bit harder for these spammers in the future.
