Is there a way to put yourself out there, creatively, on the web, and not have it come back to bite you in the arse?

I have an idea for a vlog. I want to have the freedom to have a creative and unadulterated voice, something of an stream-of-consciousness-type deal. But I imagine I’ll say some racy things. I was planning on wearing face paint to hide my identity at least a little bit. But I am weary. What goes on the web now seems to undoubtedly come back to you. It scares me. It keeps me away. And it kind of sucks, but ‘tis the breaks. I would also, of course, not have my name or anything on there. It’d be a character of sorts…something separate from me. Thoughts?
