Developers (two dudes) are super responsive and would likely release an IP customization feature upon request. Is there any service that would tolerate this [D]DOS-y kind of behavior that would feel more privacy friendly than Cloudflare?
IsThereNet [for macOS] watches for internet connection status changes and draws a colored line at the top of the screen to indicate the status.
If the other traffic is already correlated to your IP, then what additional info does an ICMP echo leak?
It tells when the user is online. This is useful for sending spam, because being on top of the inbox makes it more likely your message will be read.
To be fair, I doubt anyone’s implemented this specifically for ICMP. Instead I’d expect tracking that watches for any IP traffic whatsoever, and that happens to include ICMP.
