Matiia was not a contributor to the war besides undoing a lot of vandalism. While the vandalism contained odd messages that weren't taken seriously for the time being, it may or may not be of assistance later. Matiia was mistakened for being responsible for the vandalism and was banned. They later contacted Nicole on BDYT Wiki  questioning why they were banned. Here is the conversation about it:

What refers to vandal? Matiia (talk) 03:56, August 6, 2014 (UTC)

Vandal unmindful that refers to, but I was not vandalizing, I was just restoring the contents removed by a user who thought he was vandalizing.

PD: Sorry that is not widely understood, I do not speak English so I'm using the translator. Matiia (talk) 04:06, August 6, 2014 (UTC)

In the channel #cvn-wikia an irc channel in that community saw that eliminated much of the content of an article, and then went to check if it was vandalism. Matiia (talk) 04:16, August 6, 2014 (UTC)

Thanks. Matiia (talk) 04:35, August 6, 2014 (UTC)

chat this community or not? Matiia (talk) 04:48, August 6, 2014 (UTC)

As you can see, they are not exactly able to speak english very well. They state they used a translator to help communicate. Later that day, Matiia was not heard from again and is thought to be on another language part of Wikia.
