While that "works", what fraction of survey participants will actually do that?
I suspect that many/most folks who are reluctant to admit that they've done something won't admit it even if you tell them that other people "will" falsely admit to doing said thing so based on a coin flip. That's completely rational because I suspect that many people who haven't done said thing won't say that they have just because the coin tells them to.
