Personegation 

The act of putting oneself down or insulting oneself, self-defeating self-loathing language or behavior.

I really liked her but her constant personegation is a real turn off.

e-personation 

an impersonation or imitation that is performed in an electronic format such as a blog, email or online chat.

that was a great e-personation of a Johnny Carson monologue in your last email.
