If you deleted the entire wiki, yes. But that is a bit of an overkill just because you were logged out. Plus, wiki deletion can be done by staff only. Also, staff are the only ones that can truly hide edits (anonymous or otherwise); and they typically only do it when the user in question is under 13 years old (since they aren't supposed to be using the site to begin with).
