I often get comments on my blog that look like the following They actually contain a link to a site that has a snipped of my post on there. Is this spam, a bot or is this what a trackback (or something like it) looks like on WordPress?
Those are content scrapers which just take a fragment of your post and link back to it. I'd delete those kinds of trackbacks.
Yeah, sounds like someone's scrapped your blog. Just delete it. If you don't have it, try the Akismet anti-spam plugin and disable comments on old posts (most spammmers target older posts).
Alright I'll delete the ones that are there. I do moderate my comments so I will be able to get them without them even being published. I don't really want to disable comments because I have a couple of posts that are getting regular (good) comments that I want to keep coming. Thanks for the info guys
