nor do I think he could be called a scammer for selling software, unless he is lying about something.
The current title of his thread is: "[WTS] OpenCL Based, Optimized BTC Private-Key Cracker with Sources [WITH VIDEO]"
The first post says things like:
And who knows, this tool is giving you good chances to get one of these lost 10 MILLION US$ accounts
This project is [...] to recover lost private keys.
Working on real bitcoin network with real addresses and real coins.
This again shows you that there is an infinite number of weak bitcoin addresses.
The only thing in the first post of that thread that indicates that this isn't what people think it is, is the following:
Randomly generated Bitcoin Adresses are used (however they are all special-weak).
Which is incredibly confusing, but alludes to the fact that the program only works on special keys that no one is likely to ever find in the wild.
So, if all that isn't misleading, I don't know what is. I guess if what he's doing is acceptable, I might as well sell my "OpenCL Based, Optimized BTC Miner with Sources, 10 TH/s". It works with any SHA-256 Proof of Work (however they are all special-weak)! You could crack that 10 MILLiON US$ chain of blocks!
