My username used to be This User Has Been Banned, but I changed it in order to not actually get banned (well, blocked).
Most of the work I do on Wikipedia involves reverting disruptive edits/vandalism (I patrol Recent Changes) and warning users if they make edits that don't look constructive. I also like to do some copy editing, and occasionally try to add sources for articles.
