Earlier quoted context omitted.
Not making sense. These anon devs can still have socials. Their resume is public, and you can reach them without revealing their identity.
This is a little too risky since it could wind up with someone revealing their identity inadvertently or otherwise. If you truly want to be anonymous you should not be leaving so many breadcrumbs. All it takes is for a former employer to have a security breach and someone to point out that they found your real identity.
Now, you say any posting can reveal their identity and is too risky.
These are mutually exclusive.
