It was a little problem in my workplace, one of our system "defeated" by coinhive, so the IT check the machines, and they dont said for me a thanks, while i use your "miner" :D Not a big problem, but you know...
Next day EDIT (it was evening, and i dont want open a dictionary :D )
so, defeat is not a correct word, the system was hacked. But not our own system, it's the service provider's, maybe they have a smart employee :D
And then we got the memo, its not forbidden, but highly NOT recommended use any miner software or service, whats mean, its forbidden :)
