It is too easy to be counter-robbed when grabbing airdrops. The recent requirements for Renzo's airdrops have attracted a lot of people who are trying to get the airdrops. The score requirement for the order number is a bit too high, so getting the airdrops often depends on luck. For example, both my Op and Arb were witches, but there was no such word as witch when I was brushing. They were all based on the experience gained from brushing DYDX, so sometimes experience also needs to be iterated.
