Thanks for doing that. I have personal strong aversion to spammers. To the point where their product doesn't matter, I'll just use/help a competitor instead.
Reaching out to the occasional person who stars a project, if there's some strong overlap of stuff then maybe sure. An automatic spam approach though... that's not on. That makes starring projects a "dangerous" thing for end users, as they'd have to be open to emails for every one. :/
And yeah, it did look useful up until this point. Lets see what their response to the GH issue is like. :)
