But OK for mining!????
A miner would never jump in and out over and over again. It costs too much in gas and it takes too much time to pull your claim (plus the time it takes between getting out and back in is enough time for a mob to damage you... not smart way to mine).
The smart thing would be to run the mob away, jump in VTOL and go back to claim.
Everyone in any profession can do that and is not considered an exploit (at least I have not seen nor heard of any evidence to suggest that in MA's eyes, it is an exploit).
It's the jumping in and out over and over; that is the difference (and that is what support will tell you IS an exploit).
