Lets do it more direkt:
Eve-O Preview has been around for along time. It has been endorsed by CCP employees in the past. It has an open thread in the official forum.
Is the current forked version v5.1.2 within the rules as far as the team security knows at the current point in time?
Or if you cant answer that. Was there any official version in any point in time, that did break the rules, as far as Team Security knew about it?
