My question is how can a pingback hurt your site?
This pingback is automatic. It happens every time I use the word, "solar" as an anchor to one of my links, even internal. I am trying to rank for a long tail version of this keyword.
I have seen what pingbacks are. They are snippets of posts from my site and linking to my site. Since they are links to my site, I hesitate to unapprove them.
The problem with this particular pingback is, I don`t see a link to whomever this originated. I have read that pingbacks are sometimes spam.
Should I unapprove this particular pingback or what is the consequences of allowing them??
