I haven't gotten a phishing email, but I permanently have `ycombbiinator/-co` in my GitHub Notifications list. It doesn't display any notifications, but I have the blue notification icon. It's so annoying.
I've gotten a few similar spam/phishing notifications from github recently too. It showed that my username was tagged in the issue (along with 10-20 others).
