Thanks Eloc and Kes13a. I'm not sure how SE monitors gil transfers, but I suspect RMTs use a couple of strategies to circumvent these checks. Looking at existing services, purchases for under 10M gil (ex: 9,819,999 gil) are pretty common, so my guess is that SE only looks at transfers of 10M and higher. RMTs could very well circumvent audits in the same way that people in the US do so by making deposits under $10k.

Separately, I believe this is patch day (5.35) with new housing. Some people on the thread have postulated that market botting activity has gone up recently in anticipation of increased housing. Can anyone share their experience over the next few days as to whether market botting has started to decrease? I would think that RMTs wouldn't need to be as active after demand starts to go down. (I would do so myself, but I'm not paying for a sub until this botting nastiness is sorted.)
