I installed this and, having seen what it does, I uninstalled it. I then posted to the developer's blog asking how to block it from leeching content from content originators.
It's certainly effective, well coded and efficient. However, it's effect is to dissuade content originators from originating content because it leeches text, caches images and does not cite the originating source.
As I say, it works beautifully as a plug-in - great work in fact - with no problems... aside from the moral one.
So, my question is: how can I block this plug-in from leeching?
