                    Hello friends 
Would it be possible to install a reCaptcha on the ad comments? 
My Classipress has received many spam messages in recent days, always on the ad comments section, though I have activated the "
comment settings" >> "
Users must be registered and logged in to comment" at discussion settings, unregistered visitors continue sending spam messages. 
For now I do not want to install the Akismet system. 
Sometimes I wonder, would it be possible to install a reCaptcha on the ad comments? Is this possible?
