I'm afraid that in a small organization, where Slack is so often deployed, blocking abuse is a poor substitute for a low tolerance for abuse. My boss fired someone immediately after they made a degrading comment to someone on Slack, and in that case I think it was warranted. If that person was simply blocked by anyone involved it would have seriously broken communication with a core service. Putting a non-abusive person in that role was the better choice. It depends on the organization of course, so a blocking feature makes sense as a local admin option. In our case a "flag this comment" feature would work better.
