You could use a psudonym. That's what I'm doing.

Occasionally I shed a username and start a new one.

The admins here seem not to mind as long as I'm not voting more than once or ban evading, and the same goes for most sites.

I used to be really into comedy -- it's perfectly possible to have a persona that doesn't tie back to you, but you need to be diligent -- separate email, phone number etc.
