Hello everyone. I write posts for my blog and every now and then I receive comments on my posts. Sometimes however the comments seem odd or like they were meant for something else. In order to hopefully avoid some of these strange comments and make sure they are legit, I would like to add a cache that people have to put it in before they can post a comment. Does anyone know of what pluggin I would use for this? Or is there a widget? Thank you very much in advance.
