Some altcoin developers struggle to with having a build process for windows and Mac I offer a service to compile it so they can focus on other things if they do not want to use the time to build said environment
So there is no "vanilla" binary to check against, right?
No. But then again anybody is welcome to either compile and double check or hire someone else to compile so that they can double check.
Basically I offer a service.. they can decide to use it or not. I do not add anything to the source. And if it's uncompileable I will offer to fix the compile descriptors so they can build the files themselves.. or I can compile them. Either way they pay for my services. There is nothing suspect in what I do. Look around and you will find developers from one coin being hired by other coin either developers or bagholders to work on their coin.
This is just another service...
