I think spez has special protection against being tagged.

Nearly everyone has most of those protections.

You can whitelist a set of accounts that can message you.

You can also turn off notifications for username mentions.

Opposite actually. An example is r/drama, who was forbidden from tagging anyone with a literal hard-coded exception to the system. But spez iirc specifically said that they were still allowed to ping him .
