Don’t get me wrong here, never have I doubted the fact that you only included Gold Seller.
But the reality is that such a list cannot be used.
Sadly, banning peoples is not so simple as it sounds. Otherwise you risk a huge fiasco.
There is a process used by most modern online industry when it come to banning offenders for online abuse; the process is divided in four segments, identifying, asserting, proofing and than finally condemning.
That list you made, is part of the identifying process. But sadly, they need to assert that every name on this list is conducting illegal activity and than have to accumulate proof, to finally ban.
There is a legal reason behind all these steps.
False Positive is the worst nightmare of every online company because the last thing they want is to ban a legit person due to a mistake.
Having GM’s in-game working to ban Gold-Seller is not only a hundred time faster but also is way more cost efficiently for them than having to go through list of peoples.
Then again giving too much power to GM can cause unintended results.
So no real perfect solutions, sadly.
