The Advent event has been a total failure no one I know has been able to get even a code yet. I really wish someone from gameforge would explain why they went to this event instead of just doing things the way they had in the past. Dropping a package in the inventory when your character logs in or sending an email with the codes. These worked in the past without fraud or abuse. Why create this mess?
I suppose you don't know very many people, then.
While I don't play on Reni, I've managed to get two Advent items, one each for two toons, on Osha every day that they've been available. It's never been anything that resembled an issue, other than for the relatively short time that the Redeem Key page was neutered--until the Powers That Are engineered and installed the fix for the exploiting issues.
As for those players who massively exploited the system as it was originally, I hope they enjoy their various vacations. IMO they should have been permanent, but that's just me. I can't stand cheaters of any kind.
