I don't have a lot to go on on this report, but I do know when and where you both lost your spawn protection. According to the logs, you both lost your spawnprotection within the same second, and you were both very close to each other when you lost it, which seems to confirm Mia's story more than your version.
Now, Mia (or any mod) doesn't decide the punishment though, the system does that by itself based on your warning level. So, since this was your 5th warning for spawnkilling, that results in a 5 minute jail. About ramming people out of spawn, that rule exists since there used to be a lot of people who rammed people out of the spawnzone with a rustler. Sometimes, it would results in a death, since they were still falling as their spawn protection ended. That got a bit out of hand, so that's why this rule exists now. Since this only happened for a short period, the rule never got documented well, so it seems like not everyone is aware of it. We'll detail it a bit more when we update the rules list and how we punish for it, so everyone knows what they can and cannot do.
