When understand the system right then there is a important difference between Unity and the NA Shards, that may be considered by Smeglor:
NA-Shard: Every plot is connected to a cd-key. And every cd-key has only one connected plot. When the cd-key is inactiv for x days, the plot will be auctioned.
Unity-Shard: Every plot is again connected to a cd-key. But one cd-key can have (because of a bug) up to 5! plots connected with it.
This leads to the questions: How does the system detect how many plots a account has, and what happens when it finds one cd-key with multiple plots connected to it? And how would this effect a account that is still active, but has multiple plots?
