I had been using math.stackexchange with my real name. As I begun noticing that stackexchange community is SEO friendly, I decided for privacy reasons, to change my username to just my first name. But soon I noticed that all the mentions in the comment's section that have been made to me, remain the same (with my old name/surname).
I want those deleted, so that my real name is not searchable on this website. Deleting the whole post isn't of course a proper solution -and in many cases, the stackexchange platform won't let me delete them cause answers have been made "by people who invested time and energy". Legit enough.
I was hoping that, at least by deleting my account, my name would dissapear.
Your questions and answers will remain on the site, but will be disassociated and anonymized (the author will be listed as "user816511") and will not indicate your authorship even if you later return to the site.
But then I read this:
Your old username will continue to be visible in comments that reply to you, as well as in the Stack Exchange Data Explorer until it gets updated at the end of the week and in monthly data dumps published when your account was active.
Wouldn't be a good idea that if one changes his account username then the website updates the relevant records on the comment's section too?
It seems I am at a dead end, but I really need to sort this matter.
Thanks to Matt Samuel's answer, I flagged the comments asking to replace my full name with the current username (which is my first name) and stackexchange mods directly assisted me. Thank you all.
