Rollback (aka sponge) is a feature on Uncyclopedia that allows you to revert all edits made by a single user. It is used only to clean up vandalism. Any good-faith edits wlll be reverted with the undo button with a reason. Just click the Rollback button in Recent Changes to access this feature.

Any lame-arsed editor who is not a vandal and has proved this will be given Rollback. It is given out like candy here, unlike Wikipedia, Illogicopedia, and Uncle Pete where they have to be earned.
