A while back I was on PF from a public computer. I didn't want to sign in on that machine, so I was browsing as a "guest". I noticed something odd. In one of Evo's posts (I can't find it now), the letters "dell" were in a word, and they were linked to dell dot com. I thought, hmm that's odd. Today I noticed the same thing, but with "apple". So I did a test. I made a post with "dell" and "apple" in words and alone. When I'm signed in it looks just like I intended. But when I sign out and look at it, "dell" and "apple" are links. I didn't put the links there. Here's my test post. Does anyone else see links when they view it as a guest? https://www.physicsforums.com/showpost.php?p=3922650&postcount=15463 [Broken] Is it a problem, or a new kind of ad?
