When a card is soaked the ph of the paper is changed unless other chemicals are added, making it prone to rapid pyrolysis. Upon testing, soaking can be detected also, it is another kind of "altering" that some accept, I do not.

I am in complete disagreement with almost everything you said.
Besides that you are wrong in saying that a pencil mark can't be erased without leaving a trace. Very light ones can be removed with no trace. And quite easily I might add. I, and many other hobbyists, have no issue with removing a mark or soaking a card. It's ok to most hobbyists.
One more addition- Bill, I have several of those Staedler (sp)? art gum erasers on my desk, always. They work like a charm and are cheap.
