 :Wikias, just like Wikipedia, are edited by anonymous people. Anonymous people who might have good valid information,  and also anonymous people who might just be making things up and starting rumors - hard to tell which with people who won't say who they are. Wikipedia insists that information added is backed up by reliable sources in an attempt tell the difference. Most Wikias don't require that editors say where they got their information so information in Wikias can't be trusted as it is not possible to verify most of it. This is the reason that fansites and blogs are also not useable sources of information. :Wikias are not blocked by the blacklist because they may meet the inclusion requirements for the external links section as a source of information that can't be included in Wikipedia directly. The WP:EL requirements are are less strict than the WP:RS requirements. The external link section usually includes a link to the proper wikia for people who want a more in depth, fan centric, set of articles. We also like to encourage people to contribute to wikias as an outlet for information that might not belong in Wikipedia. :As to where to get good show information - Zap2it, TV Guide, Futon critic, Disney or Nickelodeon official sites, official press releases, newspaper websites, verified accounts of cast members or show production people (watch for posers). Avoid blogs, fansites, gossip sites, wikias.  :There is a reliable source noticeboard where questions about whether or not a source can be used can be asked. See WP:RSN.  There are some marginal cases and it is not always easy as it is for Wikias and fansites to tell whether or not a source is a good one.
