I installed Oxwall 2 weeks ago to try it out. I've activated the Watchdog plugin, and it claims to stop around 50 spams a day, so it seems to be working. But it still allowed over 120 spam bots to register on my site (almost 10 every day). So the filter doesn't solve my problem and I need to find some other way.
Is there any way to add a verification question. Like "What is the color of water?" and require a correct answer before anyone is allowed to register?
Maybe there are other anti-spam plugins that I haven't found?
Other ideas?
