To explain what is going on here:
DoctorDiscover's profile lists him as an Admin of a site called "Scp Foundation Research" with the url "www.scp-wiki.com". This appears to be scary! but it's actually just some typical stupidity on Wikidot's behalf.
The domain registration for scp-wiki.com is actually owned by Sophos, and was set up in 2011. Currently it's just a simple redirect to scp-wiki.net.
But then how is DoctorDiscover listed as an admin for this site?
It turns out, you can add a "custom domain" to any wikidot site, which just makes wikidot configure their servers to accept requests for that domain and point them to your wiki.
However, wikidot does no confirmation that you actually own the domain that you set up as a custom domain. You could set your custom domain to www.google.com and wikidot would happily accept it. This wouldn't actually WORK, because the DNS records for www.google.com don't point to wikidot, but hey, knock yourself out.
In DoctorDiscover's case, though, he happened to point his custom domain to www.scp-wiki.com, which is ALREADY pointed at wikidot's servers, and redirects to us. The only reason it appears to "work" is because it happens to already be pointing to wikidot.
Short form: DoctorDiscover is an idiot and Wikidot is incompetent. Two great tastes that go great together.
Nothing to be really concerned about here from a technical perspective but we should give him a solid slap on the wrist.
