Absurd, isn't it? I saw a thing the other day about web pages that mine bitcoins in the background. The comment was that the very fact that it was possible for this to happen in the first place - inside a glorified document viewer (web browser) - shows that the companies making these browsers don't care one whit about user privacy/security/energy usage etc.
At first I thought 1.4 million on the block list were exaggerated, after all, I'm not on every homepage in the world. But these tricky things are now also internationally networked, so it makes perfect sense to block globally. Nationally/European-wide, I have an additional list that is much smaller.
