1. An edit that is not an attempt to ruin or destroy wikis, like replacing all content with something like "asdgiuadbgsnvskjncyuceity4u769107eryfusidkhbfdsfjbsd" or "666".

2. An edit that is an attempt to ruin and destroy stuff on Wikia, like inserting swear words into an article.

3. Yes. Vandalism is bad, and happens when people try to be funny and blank pages on purpose, replacing all content with nonsense, changing the name of pages to bad names, adding offensive notes that only editors can see (ex. "" )

BONUS QUESTIONS
1. Blanking section for no reason, changing page to "LOL", replacing content with stuff like death threats (ex. "I WILL COME OVER TO YOUR HOUSE AND KILL YOU IF YOU DON'T SHUT UP!"), etc.

2. Adding missing information to an article, and really trying to expand the wiki.
