Blocky Fraud Filter IP Blocker

Developer responds quickly and communicates well. I had a LOT of questions before deciding to implement and stay with this particular app. Developer was extremely patient and helpful. I guess there's a good reason this app has so many 5 star reviews. App works very well, and is very logically set up. If you need this sort of functionality, Blocky should be at the top of your short list of apps to evaluate.
