This implementation of I2P (the Java implementation distributed on this site) includes a "Strict Countries List" which we use to decide how routers should behave within regions where applications like I2P may be limited by law. For example, while no countries that we know of prohibit using I2P, some have broad prohibitions on participating in routing for others. Routers that appear to be in the "Strict" countries will automatically be placed into "Hidden" mode.

The Project relies on the research provided by civil and digital rights organizations in order to make decisions that offer protections for its users. In this case the ongoing research provided by Freedom House has been referenced. General guidance is to include countries with a Civil Liberties (CL) score of 16 or less or an Internet Freedom score of 39 or less (not free).

Hidden Mode Summary

When a router is placed into hidden mode, three key things change about its behavior. It will no longer publish a routerInfo to the NetDB, it will no longer accept participating tunnels, and it will reject direct connections to routers in the same country that it is in. These defenses make the routers more difficult to enumerate reliably, and prevent them from running afoul of restrictions on routing traffic for others.
