Spam in blogs (also called simply blog spam, comment spam, or social spam) is a form of spamdexing. (Note that blogspam also has another meaning, namely the post of a blogger who creates posts that have no added value to them in order to submit them to other sites.) It is done by posting (usually automatically) random comments, copying material from elsewhere that is not original, or promoting commercial services to blogs, wikis, guestbooks or other publicly accessible online discussion boards. Any web application that accepts and displays hyperlinks submitted by visitors may be a target.
This type of spam originally appeared in Internet guestbooks, where spammers repeatedly filled a guestbook with links to their own site and with no relevant comment, to increase search engine rankings. If an actual comment is given it is often just "cool page", "nice website", or keywords of the spammed link.
I have been getting spam comments from Prime Industries, Inc., to the point I decided I needed to call them out. I thought it best to start small and make a phone call. Everyone I talked to was very nice, they asked for my name and number so they could call to confirm the issue was resolved. Honestly I thought, ok, I'll play along and we'll see where this goes.
I got a call back in less than ten minutes with a person apologizing for leaving the comments on my blog. She had mentioned that she saw my blog listed on Blog Rank and I was listed in the top 25 for Aviation Blogs: The ultimate rank. I thanked the person who called and let them know I appreciated the quick and classy response.
So just to show there are no hard feelings and that I appreciate a company that 'takes care of its business' I am posting a one time link on this post.
