Using a Cloud Code script, you can write a method that will reject attempts of a banned user attempting to connect, and have it optionally return a ban message based on a reason attributed to that profile. Check out the example here.
Once the script is implemented, the support team can manually ban users via Monitoring | User Monitoring | Attributes by adding the "banned" : "true" attribute, and they can also attach a "ban_reason" message.
