I came across this post yesterday:
https://music.stackexchange.com/a/52367
The answer is fine, and contains reasonable content; however, it includes a signature with a link to the author's web site. The link is unrelated to the contents of the post.
I initially edited the post to remove the signature; the rest of the content was fine, and isn't spam. However, the link has since been edited back in.
What's the correct approach here? I could flag as spam, but the post isn't really spam? I could raise a generic flag? Or I could edit it again, but edit wars are something I avoid. Or I could just leave it alone; it's not really hurting anyone, I guess. How do we normally deal with this?
