• But if I counted it, kept the money and attempted several other times to cheat the machine, this should be outrightly fraudulent as I'm taking advantage of an obvious glitch repeatedly with intent to cheat. A scam.
It is an exploit not a scam since it is a glitch/error of the machine. It has been defined clearly from the posts before yours how scam and exploit are different. You can refer to Lakai01 since he clearly differentiates the two.
There was intent in this case to move the odds in their favour assuming both individuals were working together. It would count as market manipulation to me. An exploit would be taking advantage of an existing flaw. A scam would be to use dubious and sometimes criminal means to cheat a system.
when a system is involved, it is always portrayed as an exploit. Cheating a system is not scamming but rather exploiting the flaw to one's owns advantage.
There is however a thin line between, scamming and manipulating and there would be diverse opinions on this.
The thin line between an exploit and scam is this explained well here
So with exploits I am dependent on someone else having made a mistake which I can now exploit. However, you had absolutely no influence on the fact that the error is also built in. This is different with a scam attack, where I try to get my victim to make a mistake, so I deliberately deceive him.
