I agree with Dominique, this is your typical serp scrape. A subdomain and I would also bet the domain butigdw.org/ is 404. First course of action would be for butigdw.org/ to get indexed with a legitimate site. After the culprit will operate soley on subdomains.
The number 2512 is the amount of subdomains this person is operating under, perhaps even more. For instance if your typed in xxx2512.butigdw.org you would pull up another spam site.
For xxx2512.butigdw.org there is hidden text worth viewing.
