2-3 days ago, a list of new posts included an intriguing (for me) title, rather similar to "What is this white line." I opened it and it contained a description of the problem, but no images. The post had only one reply, by Mark D Segal, who simple noted that the pictures are missing.
That was spam, Slobodan, and I deleted it and banned the poster. Like a good few spam posts recently, it had enough detail to appear superficially interesting, but for various reasons I am quite sure that it wasn't genuine. I have had cause to write to Mark, to Ernst Dinkla and even to Kevin, who have responded reasonably and nicely to some of the spam, telling them that I was about to delete the thread as spam and assuring them that I had good reason to suspect very strongly that that was what it was.
