If that is the only reason you're voting, then you can save time by not voting but telling people you did.

Being a successful conman is pretty non-trivial. I think most strategists of lying would agree that for low-cost stuff you are better of not lying, saving the risk and energy for higher payoff targets.

For example, your saying out loud in print here that this is something you would do, you have eliminated a significant fraction of the influence you would have by lying about voting here, and probably for no greater benefit than a brief flash of misplaced enjoyment of how clever you are.
