ok.....
I have to digest this --- and I had to leave the shop rather quickly before I killed the motherfucker.
I had downloaded the vanitygen program and installed on pc and we ran a few while i was in the shop that day. some take longer than others - some were fast some took a while.
well my "friend/coworker" agreed that if i supplied him the names, he would run the program, copy/paste the addresses/keys and print them so I can pick them up when I come in (I go in like once a week) he also wanted to use the program so he could 3d print things with vanity addresses and provide keys to customers - he runs a 3d printing business.
sooooo - I walk in and tell him what happened - asking if for any reason he put the pc online, even temporarily - he says no. Then he tells me he has to tell me something...
he said the program was taking too long on longer vanity addresses, so apparently in his genius thought process, he looked for other ways to generate addresses, and he came upon
https://bitcoinvanitygen.com/ and he stated he has been generating the addresses from there vs the vanitygen program on the laptop. He did not think to tell me as it the "outcome is the same".
I told him he owes me $500 and he better call any/all customers and see how many lost their funds and that he needs to have all his stuff out of the shop by the end of the week.
I have been sitting in my car for about 5 minutes still too pissed off to drive.
I spoke with minerjones who pointed out that years ago he had issues with the same site.
https://bitcointalk.org/index.php?topic=1476782.0 apparently this is a known issue.
so to summarize (I will edit my OP) this has nothing to do with the vanitygen by samr7 - and is strictly tied to
https://bitcoinvanitygen.com/ website --- which explains how it involves so many other addresses not just the ones I used.
so, I repeat
this is not related to the vanitygen by samr7the issue here is a complete breakdown of an agreed upon process - and complete disregard for my funds/funds of my children and grandchildren -well, and the funds of his customers.
I did create/use 2 from the program - for my parents. I will be in contact later today to have them check the funds - I did not save their public addresses so I cannot check them myself.
IF ANYONE ELSE HERE USES THAT WEBSITE I SUGGEST YOU TAKE YOUR FUNDS OFF THE ADDRESS IF THEY ARE NOT ALREADY TAKEN AND DO NOT USE IT ANY FURTHER
