If you brought back the cave spiders, without the Queen Spider part, it would make using a macro and not being discovered significantly harder than it is today.
I have legitimately mined more than 60000 rocks, and as much as I enjoy not being attacked while I mine, I dislike cheating macro users even more. I have recently reported macro
users several times and the admins are not up to being able to figure out if someone is using a macro or not. I even watched one admin drag a macro user and
then stop watching them before their next movement pattern had them mining in free space. I've reported macro users mining outside the mine entrance but no admin
was available to catch the macro user. Every day I'm watching more and more people using macros and the admins are too busy with more important things or just aren't
well versed at spotting the telltale signs of a macro user. But that's ok, admins should be spending their time on more important issues and it's not practical to teach them
all the telltale signs. With the simple act of bringing back the randomly spawned cave spiders to attack people mining, macro users will be much more easily spotted and macro
usage will drop way down. It would be crazy to think it would be eliminated, but right now it's just too easy to do and more and it's on the increase.
I also think the penalty for using a macro mining should be to reset their rock collection experience to zero - (revert them back to maximum time to mine a rock) and remove any remaining rocks from their inventory. The penalties today, from what I can tell, (never having received one) are really pretty minor and not much of a deterrent or punishment.
Thank you for your consideration and comments.
