This question is related to the account ban policy.
From here, we are told that an IP ban is administered when a user is banned. This issue has been brought up few times, and while they seem to be resolved, I feel like the rationale and procedure for the IP ban hasn't been explained adequately.
- Why must the IP ban also be administered if the account is getting banned?
- What happens to the users who are behind an NAT? Are they banned as well? Does SO administrators have to manually remove the IP ban upon request if any other users who are behind the NAT are affected by this as well?
