This is just despicable..
Yes its true that, if you can guess the 16 digits + expiration date + cvv on my VISA or Mastercard, you can simply abuse my creditcard.
Does that make it all right for you to do so? Well that depends on your low morals of course. But normal humans would say no...
If you find some money on the street, you are (by most standards) entitled to a 10% finders fee.
If you obtain a large bunch of credit cards with other peoples information, where one or two might work, that only makes you a thief if you end up finding them. And a pretty stupid one too.
And with you site, anyone can see you read the output first before its shown, and probably would have no problem just steal all that you can find and show a $0 to the user.
I normally spit on losers doing stuff like this and bragging about it. But luckily you have such little chance of finding anything, that way before its starting to get close to some valuables being found, most people will be using multi signature wallets for their personal storage. So why not prepare you next website with attempts to guess 2 of 2 or 2 of 3 signatures.
If it was a simple joint project to steal some seized btc by feds, find coins stuck in limbo or finding stolen money by marketplace exit scammers, I could see no problem with it. (Just stealing from a thief, hoping some profit would be given to some charities also then). But this is just; take everything you can find from whoever you can!
I really hope your own money gets stolen from this site at some point. Or better yet, the site gets hacked and someone make it show jackpot every time and people waste time looking up their "winnings" and just gets tired of wasting their time and stop using it.
If none of these things happens though, couldn't someone just DDoS this thing for a month or two? Would anyone see this as a wrong thing to do??
You can make the test and verify that it does not happen by yourself:
Generate an address and transfer
(very little) funds there.
Then search that private key on bitcoinlist, or just navigate to that page.
You'll see that the funds are still there untouched and we neither anybody else will steal them from you -
the inputs are simply not logged anywhereAs stated before, it's still not recommended to search active or addresses with funds for security reasons
