Hello and welcome to the Harry Potter Wiki! That page you just saw was an example of an unhelpful contribution someone made to the wiki (or, in this case, plain deliberate vandalism). There's no way to prevent this from happening, but there's always someone on watch to delete and revert said edits. --00:25, December 26, 2009 (UTC)
It' s not supposed to edit comments, but in some cases it is advisable to do it. For instance, when somebody gets a personal attack, some like to erase or hide it from sight. Also, sometimes it is needed to add an unsigned tag to a comment. -- 18:18, December 27, 2009 (UTC)
