SafeShip: Address Validator

I have no idea what you're talking about and this review is completely ridiculous. Most of the issues you mentioned have nothing to do with our app. I think perhaps you're having issues with Checkout Extensibility overall. There was no attempt to contact support before you left this horrible review. It doesn't block checkout by removing shipping methods and of course the checkout extensions run in JavaScript. We can't do anything about that, since Shopify controls it.

Edit: Yes, Shopify Functions could potentially be a solution. However that is not what this app is designed to be. It's designed to show address suggestions as the user is filling the address out. Also many times there can be false positives so we don't want to just completely block without offering a way to report false positives. This app isn't designed to prevent bots or anything, just to help the users choose the right address. A bot could just enter a valid address anyway.

The app pricing is comparable to other apps in the same category. You pay a base price monthly plus a few cents per order. We did issue a refund to you after your review, which we would have done sooner had you reached out via our support channels.
