There have been a number of (now-deleted) Chinese spammers whose technique is to copy text from previous posts in the same thread and then post an image, which is a link to a dodgy site. However, for me (Win7, Firefox 11), the images don't show and I just get the broken icon.
Their names are generally "normal" names with two numbers at the end, so it could be Stanley73 or the like.
If that's what your seeing, don't worry about it, they just haven't figured out how to do it properly and you shouldn't click the link anyway.
