i just got a notice that this site posted a link to an article on my site. it came in the form of a pingback notice. are they just spamming? i'm assuming that since there's a link to my site on their site, then I shouldnt really complain because its good to have inbound links. but should i be aware of anything more sinister here? please advise. thanks in advance.
There is only a trackback spam you should be aware of. I suggest you disabling trackbacks for your whole site.
