Spam is something that every blogger wants to get rid of, but unless and until some proper measures will take of, it didn’t make any sense. You may often noticed such comments on the posts, pages etc. Although WordPress comes pre-installed with some features which help you fight with spam but over the top, it is still not good enough to win this big fight. In this article, I have showcased the best available WordPress anti-spam plugins which according to me every blogger should consider on adding to their blog.
