Is there a way to just turn off SLV and not the rest of Spam X? It isn't clear to me from the documentation what other kind of fine tuning can be done.
The worry is probably that user 1 has tried to submit a lot of spam, say 20 of those 40 cases, but we don't have a user 1. I assume we deleted it years ago when we were first messing around setting up the site. The first user listed is user 2.
I wonder how anonymous got as far as submitting spam then since anonymous isn't allowed to? It was obviously spammers, as I got several within minutes, from a wide range of IPs. I'll see if it happens again, or if the site lets them through.
