Cheap and Effective I use CleanTalk since 2017 (yes, 7 years) and it blocks all known spam. It's very useful due his dynamic database, so every new dangers is recognized in few time. Really suggested.

Clean Talk is a great helper Clean Talk is a great helper. I highly recommend both the anti-spam and the security to all of my web clients. The number of spam comments is reduced to nearly zero and spam messages through contact forms are nearly non-existent for every client who has these installed on their site. If your email address is out in the wild already, it will not stop spam emails sent directly to it. Just be aware ... it stops spam contact through your site forms very well, but it has nothing to do with emails sent to you directly. I personally started using it on my own sites 6 years ago and actively encourage my clients to utilize it.

Focus on real customers, comments with Clean talk I was getting 20-30 spam comments, and user registration before using Clean Talk. This plugin does the job. Don't waste your time and energy with other plugins that have a lot of features. It is simple, handy, and does the job.

Cleantalk has taken the headache away… Cleantalk has taken the headache away from spam filtering. I've used it on a number of Drupal and wordpress websites over the years and it's eliminated bot signups

CleanTalk is worth its weight in gold CleanTalk is worth its weight in gold. Tried several other plugins, and they are either too complicated and need to many adjustments, or require loads of money to work with specific kits, hosting and plugins. CleanTalk does not do any of that. Tested the free version - no spam whatsoever, moved onto a different plugin, despite all the good reviews, spam bots are back with a vengeance. Eventually bought the subscription - just the clean submission inbox - without crypto offers and mail order company - is worth the money.
