Deny /back commands into WorldGuard regions and GriefPrevent

I'd love to take suggestions, but I don't check spigot that often

Have you ever wanted to stop people from returning to regions or claims with /back? This is the plugin for you! It adds a third-party flag to WorldGuard that you can enable if you don't want players to get back to the region with /back, and a config setting to stop players from returning to untrusted claims.

1.8-1.12 download link

Requirements
WorldGuard plugin is a dependency that you can get here.
GriefPrevention plugin is not required for the plugin to work, but DenyBack will work with it. You can get it here.

Blocked Commands
The following commands are the default back commands that this plugin will check for:
/back
/eback
/return
/ereturn
/cmi back
/cback
/dback

You can add more commands in the config

Config

# /rg flag -w "{world_name}" -h 6 {region_name} deny-back ALLOW

# what commands to deny
deny-commands:
  - '/back'
  - '/cmi back'
  - '/eback'
  - '/cback'
  - '/cmi cback'
  - '/return'
  - '/ereturn'
  - '/dback'

# the permission that allows players to /back to their death location
back-on-death-permission: 'essentials.back.ondeath' # cmi.command.back.ondeath for cmi

# if GriefPrevention is enabled, true = /back will be denied if a player's last known location is inside a claim they are not trusted in
deny-untrusted-claims: true

# set this true to deny back to all non-members of a region - setting the region flag overrides this
deny-nonmembers: false

# message sent to player if they are denied returning to a location
deny-message: '&c&lHey! &7Sorry, but you can''t return to there.'
# this will use GriefPrevention's message when a player tries to return to a claim
use-grief-prevention-message: true

back-command:
  # register a back command for DenyBack
  register: false
  # send player back to the last location that they are allowed to go
  use-last-available-location: true
  # how many seconds before player will be teleported
  teleport-delay: 0
  # message sent to player when they use the command
  message: '&6Returning to previous location.'

Usage

1. Create a region with WorldGuard. More info in the WorldGuard documentation.
2. Run the command: "/rg flags" in the region you want to be affected.
   
3. Click the arrows in chat to get to one of the pages. It should look something like this:
4. Click allow to stop players from using /back to get into that region

If you are looking at how to deny back into untrusted claims, it is enabled by default. You can turn it off in the config.

Commands
/denyback reload - requires denyback.admin to use
This next command requires the back command to be enabled in the config
/dback - denyback.back
* denyback.back.ondeath is required to be able to return to your death location
