It's trivial to ban someone from Slack. The problem with email is how there's no authentication for incoming mail, and it's trivial to spoof the sending address so you can't block them. Sure spam is a problem on most platforms, but unauthenticated ones have it orders of magnitude worse than authenticated ones. |
