Another forum im in would have to take a closer look, this could be genuine or an attempt to spam, and best mentioned to one of the modereators, i know from my experience that you can spend most of your time on the forum just sorting out various threads and links, and there are many ways of spamming...usually the spam filters do a good job but there is always some that try to get around it, and that creates a problem for genuine posters...
Still it's the community that helps sort out most of the problems as they take pride in their posts
