Yep, as an individual there is a very limited pool of activities that you can and will misrepresent yourself in, and you will tend to do that in low entropy also.
On the other hand if you are just a mostly normal guy with a dark secret, your normal life generates enormous amount of data and that's fairly easy to misrepresent the tiny bit you want to hide.
If you are an avid facebook, instagram, youtube, reddit, twitter user, it should be fairly easy to hide your plan for world domination on HN.
Actually, misrepresentation is an especially bad strategy if you're a normal guy with a dark secret.
Only if they have the truth set to compare against already.
