Most of it included my real name and email address in the executable and DLLs details tab, as well as the source code. I was the top of the little niche, and more than happy to help other developers out there. I'd help users as best as I could, but my tools were mostly geared at developers (though, users never stopped amazing me at clever unintended ways to use things)
The emails I got from this could be broken down into two categories: Actual questions about the tools, including bug reports or problems integrating it into some other project. That was about 5% of the emails I saw. The other 95% was "Program <x> stopped working! I can't find any contact anywhere expect in this one DLL, I demand you help me fix it!"
It was super disheartening, since my attempt to explain my role as someone that provided a tool or library to whoever wrote their application was responded with either "Your name is in this application, I don't care what your role is, you need to help me fix it!", or "If you didn't want to provide support, why is your email here?"
And that's, basically, how I ended up using random combinations of words on sites like this one. Maybe people with a thicker skin can deal with this crap, but I can't anymore.
