IS it possible to know who are gold sellers and be able to take action against them?

I'd assume tracking huge money swings on characters and then checking logs for where that money wentame from would be the best way. And depending on how the logs work in Ashes, it might be as easy as seeing the links between different chars directly, or as hard as trying to track every single piece of gold.

Outside of that (and obviously banning anyone in chat yelling about selling gold), I'm not sure if there's other good ways of knowing for sure if someone's a gold seller.
