I think this is really the way of the future. The best teams are not
focusing so much on roles as they are on skills. The more skills
available across the team the better.

Quick recipe for writing error messages: inform (1) WHAT went wrong, (2) WHY it happened, and (3) HOW to fix it.

The chance of someone be blocked by mistake in this screen is very high. Since the distance between the actions of Accept and Block has only a few pixels…  a small slip with the mouse and you unintentionally will block someone.

Error prevention
Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action. (From Nielsen’s usability heuristics)

Warnings are one of the common strategies for incorporating forgiveness in design.

Forgiveness in design helps prevent errors before they occur,  and minimize the negative consequences of errors when they do occur.

Road signs make roads more forgiving by warning drivers of impending hazards.
