When someone is banned, their IP and some of their neighboring IPs receive evil points. The thought occurred to me recently that you could create a map of the Internet according to evil points, and I couldn't resist doing this right away. The result is pretty cool-looking IMO. It also seems to show that the evil score system is working as expected: the vast majority of the Internet is not being forced to pay, and in the isolated sections where a registration fee is required, prohibitively-large fees are very rare.

Here's the image (zoom in):

Each pixel is a /24 address block (ie. each pixel represents 256 IP addresses). The colors are:
█ Zero or nearly zero evil
█ A small amount of evil
█ More
█ More
█ At this point you actually have to pay if you register an account in this block
█ More
█ More
█ More
█ Pretty high
█ A ton of evil, more than anyone is likely to pay

This is per block, so a single IP address could have an evil score requiring payment while its block still shows up as black here. A colored pixel indicates the evil score of a typical IP in that block.

Addresses are laid out in the standard way. So you can for example cross-reference with these maps: https://ant.isi.edu/address/

A /24 should almost never uniquely identify someone, but to be safe I randomly added, removed, and modified some of this data for plausible deniability.
