Nodus was never really /allowed/ per se. We just didn't enforce hacked clients until we got attacked. We let people use nodus for it's legal mod things like Full bright, auto fishing, and map. And to the mayor thing, enjoy a picture of me being a mod for the 5th time last year <3 . I play the game because I enjoy the server and enjoy talking to people, I don't give a poop about ranking up C;
ECC had (and still has) a system that detects when players use xray (the way is a secret as well). So, when nodus was allowed, mods had to watch players carefully for these type of players. To be honest, when Nodus was allowed, I thought it was the most stupid decision ever...it seemed to cause hell for a couple weeks xD
