As you may have noticed, if you were quick, it looks like the spammers have found us. I’ve been using standard WordPress anti-spam tools, which are limited in their effectiveness, and probably not all that difficult to program around.
There haven’t been a lot of spam posts yet, and I’ve just been deleting them (and the user that posted them) as I ran across them.
If the volume gets higher, I may need to take other measures, ones which are more likely to affect new users signing up than established members. Fighting spam is a constant game of foxes and hounds, and I’m the hound.
