Traps are lame. There's no reason to use them.

<Snipped quote by Techspert>

People having opinions about something's effectiveness or recognizing that you can't fool the same eyes with the same trick twice is the reason for lack of effectiveness? No wonder I wasn't on your side.

You probably weren't because you're evil. But regardless, it's so easy for people to barely scrape by when a plan is tried once, and even if they know it, it could very well work a second time. In the same way, if you make something physically impossible to work, no matter how good they are, it won't work. Logic is unable to be violated.
