Trolls may or may not qualify as vandals. Some think they are social vandals. These tend to be the same people that believe that Wikipedia is a sort of community.
Wiki Spammers are a type of vandal who add unwanted external links to wiki articles in order to promote their websites (or their customer's websites) in search engine rankings. MediaWiki has some Anti-spam Features. In particular most new MediaWiki installations use the 'rel=nofollow' attribute on all external links, meaning that spamming those wikis is a completely pointless thing to do!
