Most likely it's a human drive by off a search engine, so to speak. Happens from time to time. Typically means either user is not very bright or user is out to get paid. Looking at the list items in the OP, it's always possible to be spam - what ones I've checked out of the products listed are commercial. It could also be legitimate. The only way to make an effective judgement is looking at logs we don't have access to as users, and I'm to lazy to look up the privacy policy DF is using to see what access they have

I believe the "Report this post" button (it looks like a sign with a ! in it) will PM the administrators very easily for you BSDFan. The administrators here make it easy on us, hehe.
