Yeah, and wait like 20 days and 5 hours minimum. Itās not like you could easily grind that 70 or 90k after 20 days of playing. And if you sell them all in a string, I bet it would look suspicious to GMs that you have that 70 or 90k waiting for the retrieve timer and they are all useless items that you somehow managed to sell for 10k each.
And what IMC could be doing is to flag the gold sellerās accounts that buy from the AH. And if they managed to do that, all they had to do is to cancel any suspicious, or just simply all, purchases from them within that 48 hours.
If you save all the purchase data (for some longer time period) from AH in something similar to excel form, it wouldnāt be that hard to automatically detect and flag any activity that exceeds ātoo suspiciousā threshold. Something like gold sellerās account constantly managing to sell his stuff faster and for higher value than on average, or him selling rare stuff more often than average. And after that, buying useless stuff for higher than on average even if there were cheaper ones on sale too. And once you flag the gold seller accounts, it wouldnāt be that hard to just make the system automatically flag all his purchases after that.
This is just my speculation then, I have no idea how IMC actually handles these things.
