Site members can only be approved or blocked one at a time, and searched by name only. MemberBench adds what is missing: search by e-mail, filter by status, e-mail domain, join date or last sign-in, and approve, block or unblock hundreds of members in one go. Write rules that approve or block new members as they sign up, such as everyone from your own domain, and see how many members you have, who joined when and who never signed in. Your members stay on your own site.
