Add exception for UptimeRobot uptime monitoring service, see https://uptimerobot.com/help/locations/ Currently, the following legitimate monitoring IPs are listed in inbound.txt:

grep -wFf IPv4andIPv6.txt inbound.txt 3.12.251.153 3.20.63.178 3.77.67.4 3.133.226.214 3.149.57.90 5.161.75.7 5.161.177.47 5.161.194.92 49.13.164.148 52.15.147.27 52.87.72.16 78.46.215.1 88.99.80.227 157.90.155.240 167.235.143.113 178.156.181.172 216.144.248.29

Hello @schadom
After some evaluation, I've decided to decline this change. The main concern is scalability, if I accept this, other users will reasonably expect their own preferred solutions to be added as well, which would be hard to manage consistently.

Additionally, not everyone uses the same tools, so a hardcoded exception for UptimeRobot wouldn't be a universal fit.

I'd encourage you to fork the repo and customize it to your needs, it's really straightforward to do, and that was intentional in the project's design so anyone can build their own tailored list with a simple edit.

Thanks again for contributing!
