alt Hacker NewsI don't have any specific suggestions, but I do want to give thanks for implementing functionality to block pushes if the email field is *not* using an anonymized mail address.
It's one thing to offer anonymous e-mail addresses, but it's also awesome that GitHub can help prevent mistakes that would otherwise leak a user's e-mail address. I am not sure how many people try to be privacy conscious on GitHub, but I assume most users don't, so it's nice seeing this little feature exist.
It gets more complicated when commit signing, the widely broken web of trust (for the signing key) and similar are involved.
And not all devs want or need anonymity on github.
In general just because information is publicly accessible in some form doesn't make it okay or legal to abuse it (accessible doesn't mean any form of usage rights are transferred to you weather it's in context of GDPR or in context of copy right).
