I have never had any problems with spam in my comment sections. I have always allowed "anonymous" comments to be made, and I really hate the word verification...so I choose not to bug others with it on my blog.
It changed for me this week. I have had a bunch of spam...very annoying. What is weird to me is that they choose a post from July to put the spam in. Different advertisements, but all the same post.
Does the word verification bug you, like it bugs me? Should I just turn off "anonymous" comments? Or should I just deal with it, because honestly it takes me like three seconds to delete them permanently?
