Allow only moderators to remove modlook tag

[vladytimy]

Currently, if someone reports a topic, the tag modlook is added. As far as I understand, the author or anyone replying on that topic can remove modlook tag from the list, before a moderator has the chance to review that report, so unless the topic is reported again, it stays in the wild as it is.

The ability to remove moodlook tag should only be available to moderators.
Maybe an extra check user_can( $user_id, 'moderate' ) when modlook is removed from the list of tags would do the trick.

Perhaps it would be better to remove this as an allowable tag and allow it to be set/reset only via the "report topic" button. Anyone could report a topic, only a mod or above could click the removal button.

Replying to sterndata:

That is even better. Marius & Dion had the same idea. (see ​chat)

To keep the implementation of the Modlook Tag View, maybe it has to stay a tag, but don't show it in the tags list anymore.
