People can tell which strategy you are using, and usually the things that are ‘bad to show’ are bad for you to show, but other people would be perfectly interested to see them. So it is less cooperative, and people may respond to that, which may on a longer term view be bad for you.
Related to this: if you are hiding things, then people may detect that you are hiding them, but not what you are hiding. As a result, they can’t tell whether you are hiding something relatively innocuous or something worse, and may intuitively trust you less. If your strategy tends towards revealing things, then they might see the bad things but be overall convinced that you’re not hiding anything that would be even worse.
Some people will likely also find your bad sides relatable.
At the same time, sharing too much too quickly can also send a negative signal, as it may suggest a lack of discernment about social norms.
