There is something called "Juicio temerario" I don't know the exact translation to English but I will try to explain. It means when someone who doesn't know you, your reasons or your situation comes to think you are doing something for a bad motive or that you actually ARE a bad person.
That happens everywhere/everyday. Sometimes it doesn't go so far, bit this guy took it the next level it seems...
I am happy you could solve this like a gentleman.
And I hope people (including me) could always give others the benefit of first thinking they have good intentions or at least doubt instead of hardly thinking they are evil.
Congrats for this awesome project! I will stay around trying to contribute :D
