I'm not an expert, just a guy with a website who was fed up with the amount of SPAM that appeared on my site. Stop Spammers to the rescue. It has worked flawlessly since I installed it, working on its default settings. I can't comment on the support as I've never needed it, which to me is a great advertisement for the product. I'm sure there are loads of additional features that I don't use but for the man in the street, it's a great plugin.

I used Stop Spammers on 3 of my WordPress websites and I find it to be very effective in stopping these annoying spam entries into the registration, comment forms or more. The plugin has a lot of options that can be customized by your preference, special situation and level of false positive you're comfortable with. Specifically, I like the option to allow the actual users who get blocked to fill out a form to get whitelisted. I recommend this plugin warmly to everyone looking to protect their website!

The free version has options that in some others are paid, that I loved. Easy to use, very intuitive. But to be honest the paid version has no comparison, it is very good. It is a very affordable price.

I really appreciate all the pre-set options and the ability to customize them. Thanks for this plugin for many years. I'm glad it's got new life from being adopted by a new plugin owner. Looking forward to its continued development.

I like the fact this plugin uses multiple sources of repudible spam blacklists. This provides redundancy instead of only relying on one, like so many other competitors. Suggestion: I would like to be able to input the URL of a custom IP block list and have this plugin block those IPs as well. The plugin should update or ping this IP block list for any changes and apply them.

Solving the age-old problem of comment spam that has plagued every WordPress developer since the dawn of time. These parasitic track backs and authority suckers are pervasive and disgusting. This lightweight little plugin is one of the first I activate on any site I create. Why pay $50 every month to protect your sites? This is a very budget friendly premium plugin at $50 for unlimited. It's a no brainer.
