JQL for "when comment NOT by Assignee or Creator"

[Loren Robeck]

I'm trying to add this to the settings of one of my Slack integrations. I want to reduce the noise of the channel a little by only posting updates when:

a new ticket is created,

OR when a comment is created by someone who is either NOT the assignee or NOT one of four team members. 

Is this possible? (in a Next Gen project, fyi)

If you have ScriptRunner take a look at the steps

I think assignee might be a valid field to check for
