It seems users installing this software may not have read your intro or blog post describing your feelings towards web mining and are opening issues like #141 #179. Have you considered adding a sniffer in addition to your blacklist like MinerBlock?

Also, what do you suppose the chances are an extension like this could get hacked like the MEGA Chrome Extension was last year? That seems like it could be a problem for user privacy and security in general. What are your thoughts?
