Today I received some spam email. This was the first spam mail to arrive on my "arduino" email address. Since I use dedicated email addresses for everything it is absolutely clear that the only way to get hold of this address was through the Arduino forum.
In my setup my email address is set to "invisible".
It is not a really big deal because I will change the address. However I am always curious how the address might have leaked.
Has anyone and idea how this might have happened?
