Fair enough, I suppose someone could snoop because there seems to be something going on with their spouse, and the spouse isn't sharing. I don't believe in snooping, never have done that. Many people snoop in dating situations or relationships outside of marriage, I don't think it's something that strikes in marriage, personally. Why not just ask your spouse what's up?Are you sure?
There is nothing in the OP which states snooping and spying cheating only. It is what people went to in their own posts. It is in the general area of the forum, not CWI, I answered your question with general reasons.
