Hijacking words in posts

[Spinner]

Hi guys:

I notice that a few posts are showing up with some words hyperlinked to websites that I assume have nothing to do with the poster.

I also have a website that has a page with one word that has been hyperlinked to google search and not with my approval. I have not talked with my web manager yet about it but just wanted some comments.
