People teleport hacking mining nodes

[Stilp]

Just witnessed seven different people teleporting between mining nodes. Some were even appearing under the ground to mine them. I know hacking exists, but seven appearing in front of me within a five minute period is a bit worrying. If this is happening to this extent already, god knows what it will be like a few weeks/months down the line. This is going really screw with server economies (if I can randomly see seven within five mins at one spot, how many more are there around the world?).

I of course reported them. Have recorded a video too, but not uploaded it yet (has only just happened).

EDIT: An eighth one has joined it. I give up. Spending more time reporting than playing this morning.
