Thank you Nigel for your help.

Btw, Is Disable Self Pingbacks will affect SEO?

1. Disable pigbacks
2. Trash all ping backs that have appeared in the post article

1. Disabling self-pingbacks doesn’t affect SEO
2. All other pingbacks should be treated the same as comments. Some are good some are bad depending on the website they come from. How you handle them is up to your personal preference.
3. If pingbacks are enabled it takes a little extra work to manage bad pingbacks. You can also research how to disavow links on Google Search Console.
