 * Hello, Ben!
 * The latest version of Zero Spam doesn’t work with caching plugins.
    As far as
   I can tell, the problem is caused by the ‘key’ value stored both as a cookie 
   and a JavaScript variable. When a caching plugin is active, the cookie value 
   changes, but the JavaScript variable doesn’t, making every comment or form submission
   fail.
 * Also, please consider removing all options on uninstall. (like you did in version
   3)

 * Thanks for the catch, got a fix for that in the upcoming version: [https://github.com/bmarshall511/wordpress-zero-spam/issues/177](https://github.com/bmarshall511/wordpress-zero-spam/issues/177)
 * I also plan on adding more features in the coming days including the ability 
   to uninstall. I’ll add that to my list: [https://github.com/bmarshall511/wordpress-zero-spam/issues/179](https://github.com/bmarshall511/wordpress-zero-spam/issues/179)
