If you're annoyed by the deviantart tier shit that has been popping up lately on pixiv you can use ublock origin and custom filters to block it when browsing. Under "My filters" copy and paste the following:

!Block pixiv artist from web searches.
!example
!www.pixiv.net###root li:has([href="/en/users/artist_ID_here"])
!Copy and Paste artist pixiv ID into artist_ID_here
