The real surprising thing here is that, if a person is capable of doing something like this for a faucet, how much developing skill does he have that goes unused? I mean we are talking about a guy who built a software that tries the faucet automatically, then if he busts switches the account and IP/VPN to try another account and continues as long as possible until he actually abuses the faucet, now that is some software developing skills right there, I personally wouldn't know how to do that and I have been a web developer for years! So we are talking about a guy who could use these kinds of skills he has on something much more productive instead of destructive and could make a decent amount of money, yet he uses his powers for evil and not for good, which is shocking.
That's the problem, there's so much untapped talent out there. Some of these people will talent end up using it for nefarious purposes.
There's actually an entire term devised for itcriminal ingenuity.
With that said, creating a script to automatically claim faucet and switch IPs is not exactly rocket size. Anybody with basic python knowledge could do it, and you could get a script kiddie to whip one up for less than $100.
I do not think you are estimating the talent for a pyhton knowledge enough to build a script that could claim faucets and gamble and if fails switches IP's and then tries the same thing again and do this over and over again enough to make money for it.
I am not saying its not 100 dollars, that could very well be the issue there, but that is because the whole world is your rival there, if you sell that for 5000 dollars then someone else will do it and believe me there are developers all around the world. However a person who is capable of doing that would also be capable of doing other stuff and that means that unless they live in a farm county or something they could find a job with that talent.
When you sell a script the whole world is your competition, when you apply for a job at a company, only the people who can go to that office is your competition so it is in fact "criminal ingenuity" like you said to use that for selling TOS breaking scripts instead of applying for a job at a nearby company who needs developers.
