I discovered some time ago that some kind soul decided to try to give my site a black eye by "log spamming". I was checking links on Yahoo and found a reference to my site on a very weird site. I investigated and found that some guy thought I had managed to spider his logs and place a link to my site in his logs.
The fact that I have no idea what that is or how one goes about doing it is neither here nor there. The upshot is that once you are linked, like it or not you are stuck with it ... seemingly forever.
It was obviously a competitor trying to sully my reputation. It didn't seem to help or hurt my site (noticeably) one way or the other so after many months and dozens of unsuccessful attempts to convince people that I hadn't done whatever it is that you have to do to spam someone's logs ... I finally gave up. Years later, those links are still there.
Unfortunately, even squeeky clean sites gather moss as they tumble through the internet. Its just something we have to live with or go through the process of starting over with a new URL. I don't relish that idea at all and who's to say it wouldn't happen all over again!
