It's up to Frontier to tell it's playerbase if there are exploits in the game that player's shouldn't be using......until they do this then these are just bugs & player's are working within the current game mechanics as presented by Frontier.They attempted to patch the exploit and failed. I guess they will try again. Till then to me it's an exploit and I will wait till it's posted by fdev as patched.
Maybe Frontier should communicate with it's playerbase more, if they really want them not to make use of these 'bugs'.
BTW, I have no interest in this type of Mining technique & have never tried it.
