Kazadure (W:10 days | S:4 days) has spent the entirety of their site history reposting the same article to the 5311 slot.
On October 27th, they double posted the same article to http://scp-wiki.wikidot.com/scp-5311 and http://scp-wiki.wikidot.com/scp-5311-what-got-mars. The latter was summarily deleted, with the former going through the standard deletion process. Relevant deletion threads are here and here.
Today, they reposted SCP-5311 with little to no changes from what could be observed. They included the following comment in the discussion page:
Sorry for being a brat guys but I feel this is finished work now. Give honest opinions
The article was summarily deleted for being a repost (relevant thread here). As an aside, they initially posted to the draft forums without greenlights as one of their first actions as a site member (http://www.scpwiki.com/forum/t-13834698/draft-scp-5297-holographic-transmitter#post-4802876). Their history doesn't indicate the best understanding of the site's rules, keep an eye on.
