I'm extremely scared my career is fucked. My GitHub username is linked to my real identity. However if someone were to search my username up, the reddit profile of someone who posts regularly on porn subs and tweets inflammatory political shit appears.
Searching my name brings up that GitHub. I changed my username on GitHub, but searching my name still shows some Chinese github archival site that links me and my old GitHub name together. I tried emailing the admin and he won't remove it. There's no plausible deniability because that site also lists my projects.
My name is also very unique. I'm so scared. This has been stressing me out for the past few weeks.
There could only be two people in the world with your name, you and the other guy, and the situation is the same. "That's not me" is the only thing you need to say. Professionals will understand.
