To answer the original question, you can absolutely create a new wiki based of an existing one. As long as it doesn't break the Terms of Use, wikis with duplicate subject are fine.

"I was told by Wiki Staff that 2 Wikis on the same topic is allowed, however is it is an obvious Cut and Paste Transfer (and reported) it may be regarded as Plagiarism and the Wiki 'Stealing' would probably get removed or merged to the Original, plus I am sure disciplinary actions of the Plagiarist may happen as well."

In this case you must attribute the original wiki. The best way to do this is via the Special:Export and Special:Import tool.

"He went over to the FF Answers Wikia specifically to harass that user with vulgar and homophobic slurs, then used her upset response to claim she was responsible"

If this is true, it is against Wikia's Terms of Use and you should talk to staff about it, if it is false - then please don't say it.
