I'm "Rarely".
I don't count as cheating any change of rules that all players agree on.
To me, cheating means intentionally acting against the rules without the consent of the other players.

If it's a game for fun, that seems like a real contradiction of the intent of the practice. Winning is usually meaningless. What matters is connecting.
