I think it depends on what you're doing with it. John Mackey (of Whole Foods) caught some significant flack and legal trouble for talking about Whole Foods stock very glowingly under several aliases. That'd be a problem.
But, if it's just for "shooting the shit", about random topics unrelated to your bottom line, I can't see that it would cause any trouble.
