I'm using cleantalk from last 2-3 months.
1. Prevents spams users and also checks database to find out old spam users
2. prevent spam commenting..
1. I see this plugin can not handle fake orders. I'm sorry to say but after installing this plugin first time i got many spam orders.. and continue getting..while i'm using latest version of woo commerce plugin..
Warning! This plugin need pays. For free work only 14 day!!!
helped me a lot with my site
At first this seemed great, because it does block spam. Unfortunately, users began complaining of seemingly random error messages when trying to register accounts and place new orders.
I tracked the problem down to this plugin, which was rejecting their legit requests as spam, and not providing them (or me) a useful error message. These false positives definitely lost me a few customers.
The free version gives you up to 5 comments that are not spam a day. While typically I have less then that, I do have post that get more then 5 real comments. They then go into manual moderation, with the rest of the spam.
I didn't test it further as I wasn't willing to register just to test it out. If I can't find anything better maybe I will.
