Our previous implementation used a simple `blocked_domain_array.include?(hostname)` so some values were not matching. Additionally, in some configurations like ours, we'd used "cat.*.dog.com" with the assumption we'd support globbing. This change implicitly allows globbing by blocking "http://a.b.com" if "b.com" is a blocked domain but does not actively do anything for "*". An upcoming change might include frontend validation for values that can be inserted.
