it is in Ten Commandments 1) Thou shalt not interfere with the works and files of other people.
2) Thou shalt not sneak around in other people's computer files.
3) Thou shalt not use a computer to steal and do negative things.
4) Thou shalt not use a computer to bear false witness.
5) Thou shalt not copy or use proprietary software for which you have not paid.
6)
Thou shalt not use other people's computer resources with no authorization or proper compensation.7) Thou shalt not appropriate other people's intellectual output.
Thou shalt think about the social consequences of the program you are writing or the system you are designing.
9) Thou shalt always use a computer in ways that ensure consideration and respect and safety for your fellow humans.
But they get compensation, whether or not thats proper depends on each individual user.
but in seriously i am not a law student so i can not tell you where exactly in the law says that but i say this because of incidents like this:
"Gaming Company Fined $1 Million For Secretly Using Players' Computers To Mine Bitcoin"
this was a 2013 event. google it and you might find the law that covers it.
This is to odolvlobo as well.
I am no law student either, but the CS case is completely different. They forced participants of a tournament to install software in order to detect possible cheaters. The software in question did not openly state that it was also mining bitcoins and the software in question did mine bitcoins while it was not "used", as in while they did not play CS, but
watched porn browsed imgur to relax for the next game. Thats a big difference. The way I understand OP they are stating that the CPU (possibly GPU) is used to mine certain coins, be that in the small print or a big red warning does not matter IMHO. If you accept terms without reading them, well prepare to get paypaled. Additionally OP is not injecting any software that runs in the background into the users machine, but once the browser tab is closed and the user stops playing the mining algorithm stops running.
