remove url

Hi.
I don’t know if it’s possible, but can you please remove my site URL from this topic?
https://ww.wp.xz.cn/support/topic/1-button-w3c-validation?replies=11

The URL that I would like delete is http://www.guidedolomiti.com/ wp/

It is a wrong URL, but it’s still in Google (404)
Thanks, and sorry for my bad English.
Ciao
