Not parent, but I'm doing the same thing and I have had 5 leaks out of (currently) 387 accounts over the past 4 years (which is when I started doing this).
Oh and none of the involved entities ever acknowledged the leaks. I'd also be highly interested in the rates other people encounter.
I've been doing the same over a similar time span. 5 years for me. However, i am yet to find any leaks.
I get a ton of spam, but they ALL are sent to my publicly listed email address in my git commits. I'm seriously considering turning that email into a honey pot.
Could be. If they sold the email addresses, that is one reason they would not "disclose" it, it was just routine business (and not business they are eager to disclose, although I suppose it's mentioned in some fine print in their privacy statement somewhere, hypothetically, maybe).
