CleanTalk, the solution to Spam on WordPress?

The shock comes when you open your website to registration, subscription and comments and a few moments later your site is flooded by spam via bots. WordPress’s own defenses are much to weak to deal with that. I tried CleanTalk for a few days and decided to subscribe to them for a rather small sum of money. I will keep you posted about the outcome of this investment. About to now, only very positive.
