Writing down exposed cards

[NYCNative]

I realize the furor over software that recalls exposed cards in Stud games. I am curious what somone would think if they knew that their opponents writing this down while playing against them online. This is old school paper & ink here.

Taking it a step further, what about a program that doesn't do anything automatically, but allows you to click a card and a number and have it display the cards for each player.

Finally, if someone was taking such notes in a live game/casino, would they just be mocked or would they be escorted away?

Note: I don't do any of these things but I was curious about the ethics of it all...
