Regarding Tiny Village Wiki and Tiny Castle Wiki, it is because they have not been updated since 2014 and 2015 respectively. Since then, Wikia, Twitter, and Facebook have changed/retired widgets so the old methods don't necessarily work anymore. I would suggest reading Help:Social_media_integration in order to see what is currently available. Regarding Twitter, Wikia has stopped allowing the use of the verbatim HTML tag due to a series of serious cross-wiki vandalism incidents that exposed the risk of allowing use of that tag. It has been replaced with a Twitter widget; as can be seen here, on the Tiny Castle Wiki.

As for TinyMonsters Wiki, it is a similar story to Tiny Castle Wiki except that Maximum Ride Nudge, one of the admins, recently removed the social media portion entirely.
