Say my name enough times in the mirror and I shall appear.
First of all, just to say, I will not be going into the specifics of this case, as I'm broadly of the opinion that the fine details of a ban are between the admin and the players involved. If anybody involved in the ban wishes to talk about it, that's their right to do so.
I can confirm however, that I banned a string of colonies on M2 last night, and that one of them had a sizeable backlog of previous eras and medals under their belt, and the rest of the colonies had few/none.
I will note that the evidence used to close this case was pretty straightforward boilerplate stuff that gets checked on every era. It's even partially automated.
I have admined several eras for the more experienced involved player before, and I have never come across this in my time doing so. In my experience, rulebreakers tend to get better at hiding rule breaking, not worse. As such, I have little reason to believe that this was a repeat offence. So far, all evidence suggests that this was the first time any of these accounts have been involved in this specific activity. Obviously that is my perspective based purely on the information that I have, not a claim of infallibility on my own part.
Hope that clarifies a few questions.
