Free, Nice, but..

I want to be as honest as possible. The plugin is good.
Tried this plugin (and its service) a while. Nice layout and better than another similar plugin.
However, after seeing some ads appeared, done in an unethical way, I uninstalled it immediately. Misusing the plugin to inject and infiltrate unwanted links/ads is not something anyone can accept. Opting out is a pain, and it seems that doing this is hardened.
Giving something free doesn’t mean you can do anything you want…
