I think this applies more to high cost items not bulk items. So although you have high gold sale if you sell them it is split up into multiple smaller transactions so it should not be a similar situation.
The way the system works is not fletched out cause if it was, then gold sellers/rmt use it to make better ways to bypass the system. So everything will just be based on information we know so far. All we know is there are multiple claims that there are false ban flags on high cost items being sold. Not on high sale price due to bulk items.
Players who make gold flipping the market would also be on steriods with cheap gold, to be able to flip in bulk.
Now did players rmt to dry up sectors of our market? Idk, but i do know that being an honest crude mushroom disciple allowed me to sell for alot more then i paid.
If ags has no measures for the market, i would also question why not.
I wouldn’t worry. You’re not receiving a whole bunch of money AT ONCE selling mushrooms. Gem, or BiS accessories’ gold, on the other hand, arrive at once. That’s why the system flags those transactions.
