We moderators have been staying on top of it, but right now we are being swamped with spam. I suspect they are testing, many of them are obviously bots with nonsense messages (formats are consistent over and over). There are a lot of conversations in the background in the moderator forum working various issues, and thanks to Jrap and Bertus things are coming along. I'm staying logged in even when I'm not here to see if it can discourage some of the spammers, it doesn't seem to impress them much. So just keep reporting the threads as they pop up, and like the gopher game at Chuckie Cheese we keep nailing them. I may go back to invisible mode like I used to on the other software, so they would try it while a moderator is watching. It is hard to say which is more effective, but it does feel good nailing them while they are in the act.
