User LHill (wiki member for 203 days) posted an article in the SCP-5046 slot that appears to borrow its concept from an article by a different author that was in the same SCP slot until it was deleted earlier that same day. Both articles are very short, but have a number of notable similarities - both SCPs are about a wendigo that inhabits a house and in both the wendigo lures victims into the house before killing them.
LHill does not credit anyone for the concept in a post or info module.
Due to the close timing, similarities, and both articles having the same SCP number I reached out to the author of the older article to find out if they had given anyone permission to rewrite their SCP.
ETA: User replied. They did not give anyone permission to rewrite their article.
