"Delete Spammer" from "Flag" menu returns 403, doesn't work

[Osama]

I reported the same issue here:

https://meta.discourse.org/t/delete-spammer-on-admin-flags-doesnt-work-for-mods-if-show-email-on-profile-setting-is-turned-off/66785?u=osama

In short, this is only an issue for moderators when the show_email_on_profile site setting is turned off which is the default.
