Account anonymization/deletion

[Kiahdaj]

I was asked to post this here after PM'ing an admin, and since Volf has his PMs disabled.
If you could, I would greatly appreciate it if you would anonymize (that is, change the username to something else entirely)/delete my account such that my account/posts no longer appear in search engine results. I am trying to clean up my ties with past online communities, and this would be a great help.

Thank you very much
