Professional and trustworthy so you can relax! I manage several websites and few dozens of plugins at the least. If there is only one WordPress plugin that I should recommend, then without any hesitation it is CleanTalk. It’s very straightforward, very easy to use, stable. The user dashboard looks kind of old school but the magic happens under the hood. No more spam! That’s it! That’s the promise of CleanTalk and it works. And if by any chance, you still have few spam skipping the net, they will be here to assist you and fix the problem. Also, they have the best customer service you can imagine! Far beyond what I could expect. Thank you!
