This question already has an answer here:
I like to use my real name and photo on some Stack Exchange sites that are relevant to my career (e.g. Stack Overflow) but use a pseudonym on other Stack Exchange sites (such as Gaming). Partly, because I want that if possible employers Google my name they see relevant things for my career, not me commenting on games or that sort of stuff.
Right now if I go to a new SE site automatically a new account is created with my name. I can change the name and e-mail, but there is still a tab with my other accounts. Is there a way to hide this?
I found this question: Can I hide associated accounts on my public CV? but that is only about CVs.
