SpamKarma2 just notified me that I had a spammer trackback comment (a score of -7 because it didn't include a link to my site). The trackback looked authentic enough, so I rescued it but it got me wondering about Trackback Etiquette.
I thought all trackbacks and pings contained links to the trackbacked/pinged sites (unless they were obvious spammers) but when I looked it up in the Codex I found I was wrong.
Okay, so Blogger A might want to let Blogger B know they are writing about a related topic and throw out a trackback without giving Blogger B a link. I can see how I MIGHT do this (but probably would not) with somebody I know and who knows me.
But I can't see sending an unlinked trackback as a first time contact. It seems kind of... pushy.
Wouldn't it be more... I don't know... tactful?... if Blogger A commented directly on Blogger B's post or sent a pingback first, rather than sending out an unlinked trackback? Otherwise, isn't it almost like saying: "Rather than comment directly or link to this, I'll just add a link to my own post."
Which kind of smells like spam.
