Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
Ping backs are considered good for SEO when linked relevant content. If you have spammy pingbacks, then activating akismet antispam is a good step to take. You can refer to the following article for how to handle comment spam: https://www.wpbeginner.com/wp-tutorials/how-to-put-a-stop-to-wordpress-trackback-spam/
I hope that helps.
Thank You
