Ability to "mute" or otherwise ignore/reject reports from specific users

[bnewbold]

There is an abuse vector for users to harass moderation services by posting bad content in reports (including appeals), possibly many times. If this happens, it would be helpful for mod teams to be able to reject or ignore new reports from that account, either for a fixed time period or indefinitely.

This is similar to the existing "mute" functionality, which applies to a "subject" (not reporter).
