Thanks jazzgirl for noticing my post.
Not only was the thread removed, but I was banned for posting that link.
As Norah explains, it was thought to be spam.
(I posted the same message on another board without any repercussion).
I hope that the admin changes their process.
Never be too hasty to ban poster for life, when you may be doing something in error.
Just stop them from posting. Not looking.
For almost 48 hours, I could not even look at the threads for the puzzles I was solving.
Now I am "unbanned". Phew!
Surprisingly that same puzzle appeared in a tech site called Gizmodo. They provide valuable information on tech issues. So I had no reason to think that I was doing anything wrong in posting the link.
But I am wiser now and I hope so are Norah and Ash.
