Testimonials

  • "One of my favorites"
  • "this is a clever idea that I think might work well"
  • "I haven't had a single comment spam in my comment moderation queue for over a week now. I'm feeling the love!"
  • "The least annoying one I have found"
  • "this thing was a trivial install"
  • "a fancier technique"
  • "Comment Spam is a thing of the past, and I owe it to Spam Stopgap Extreme. If you use WordPress, I highly recommend installing this plugin. It has completely eliminated the comment spam problem I was having. I no longer need the spammer Tarpit plugin, or anything."
  • "Why am I not worried about comment spam anymore? Because of my awesome new blog plugin, Spam Stopgap Extreme. This baby blocks any bot trying to post to my blog. No blacklists, no moderation, no 'spam points', no nothing. You won't even know that it's working."
  • "I haven't had anything to 'deal' with in several weeks. That's a nice thing. I've also had a bunch of folks leave legitimate comments that have gotten through. It's all good."
