New web server?

Just recently my ad blocker has been alerting me to another website attempting to run scripts when accessing BC. This is yourbigcloset.com.

I'm assuming this is innocuous but I'm also aware that this is exactly what bad people like to do to get into places they should not.

Can you confirm that this site is kosher and should be permitted? Can I ask why another URL is required? Why can't this go under bigclosetr.us?
