I trust the players I'm playing with to follow game as laid out in session zero that they agreed to. I'm also trusting them to not fudge dice rolls (when not using the VTT supplied one), to not change their character sheet, or not to add gear or stuff they didn't actually have. I tell players all the time in session zero - you're only cheating yourself if you're fudging dice, saying you have gear you don't, etc. This isn't a competition, and we're not playing to "win DnD".
