I do exactly the same as lucaaa but i personally consider it a bit rude. I understand the player wants resouces but the mines are 99x99 X.X. I also find it annoying in most cases. This is the reason you will hardly ever find me in a mine anymore
PSA: If you get scammed, don't whine at other people that you did. Just move on, accept the truth that you had a fault, too, and work your way up again.
This guy randomly came up to my realm and started whining about being scammed because he participated in a drop game. I just told him his experience was a lesson for him and that he should accept that, move on, and work his way up again (and he lost like a few diamond stairs and a spook-inna-box in a drop game). But no, he kept whining that he wasn't dumb enough to fall for it and it was all the scammer's fault.
