How do these 3 elders determine what would be offensive to the congregation?
The three elders opinions are the first determination off what is offensive to the congregation. After that if the poor soul who is reinstated and gets some "privilege" returned causes some gossiping busy body to get their undies in a wad that "privilege" will be yanked PDQ. At least that was my experience thirty years ago. Just another of many reasons for getting FedUp.
