Sean, I'm not against pressing, and I applaud Tupenny for posting ahead of time books were pressed.
I think what happened in that thread, possibly, was an innocent question may have been misread.
The way I took Pep's question, if I may frame it based on perception, was, "Hi. I think it is great you mention a book was pressed. What do you look for when trying to detect pressing?"
Just the way he asked it, it may have come across like a challenge. At least, I hope that was what happened versus beating up on a thread when a seller is trying to be up front about book prep work. Then that would be totally wrong!
But knowing how the pressing debate can get heated, I probably would have asked that question via a PM. I'm still leaning towards it was such an innocent question, Pep didn't realize how it came across.
