I will still be in contact with Wikia on this matter. I will pass this blog along to Wikia staff so they can either confirm or deny if the other accounts you listed are also coming from the same or 2nd IP.

And, yes, it is easy to spoof an IP address, as easy as going to a coffee shop or any other place that has wifi. Since it is that easy, placing permanent blocks on these accounts can't happen, since that would make anyone else who visits such free wifi places unable to contribute on the wiki.
