Incidentally, I don't think this applies to FileZilla, which requires exactly one key or other authentication method per site. It does apply to OpenSSH because it tries all available keys in cascade until one succeeds. Profiling Even though I2P hides our addresses from each other, there are many ways to deduce which individual users exist and who did what.
