Hello, I maintain the "Black Box Proxy Block" service which is used by this plugin. I wanted to inform you that our URL has changed. In /src/main/java/com/certox/Core.java, instead of:

this.activeBlacklist.put("http://www,shroomery,org/ythan/proxycheck,php?ip=", "Y");

you can avoid a redirect if you use:

this.activeBlacklist.put("http://proxy,mind-media,com/block/proxycheck,php?ip=", "Y");

Thank you for your consideration and I hope you continue to find this service useful!
